Various KDE apps crash with signal 7 in KPixmapCache::Private::mmapFile()

Hi,
Any idea how or when this crash happened? Thanks in advance!

Sorry, I don't remember. It may have just been a seemingly random occurrence.

I experienced this too. It happened after I launched System Settings using Krunner. But prior to that, I tried to launch it using raptor-menu but nothing happened so I used Krunner instead...

Hello there, for me the bug hapenned when The plasmaoid "Last peripheral USB plugged" detect my external HDD, strange...
Sorry for my english.

Hi!
Well, I don't think I was doing anything with USB when it crashed, if I
remember correctly. Anyway, it happened only once so far and might have
already been fixed in Qt4 or KDE libs, which have been updated recently (and
there was a large update this morning as well). I will keep watching.

Good luck!

I had this same crash a few minutes ago while trying to open konqueror. Everything on the screen froze except for the mouse and I had to r-e-i-s-u-b out of it. I also had a similar crash a few days ago while trying to open konqueror. You can see my prev. bug report.

I'm using 64bit kubuntu 9.04. let me know if I can give you anymore info.

Same crash again while closing Firefox after making the above report. This time apport didn't catch it. Had to do the r-e-i-s-u-b again. I should also include that Kubuntu Intrepid 64 bit gave me the same constant crashes to the point where I decided not to even give it a shot for more than a few days.

And again. Same popup as in the above "krunner crashed with signal 7 in KPixmapCache::Private::mmapFile()" without the screen freeze. Maybe I should never close firefox again. Just kidding - I'm going to killall firefox this time.

A fix has been committed for KDE 4.3 beta2 and for KDE 4.2.4, though it just missed tagging for 4.2.4 so we may want to cherry-pick that ourselves for the PPA packages.

This bug was fixed in the package kde4libs - 4:4.2.90-0ubuntu1

Still happening in KDE 4.3.0.

Happened to me on Karmic (installed as alpha 4) after reproducing and reporting <https://bugs.kde.org/show_bug.cgi?id=206890> "Bug 206890: krunner doesn't reliably show newly installed applications krunner doesn't reliably show newly installed aplications"

The crash happened a minute or so *after* playing with krunner, and interrupted my fullscreen game of starfighter.

PS please ignore or delete the incorrect bug watch which Launchpad "helpfully" added after my comment above, without asking me.

I'm also affected.

When starting Chromium game !
Screen change resolution and just after it many crash arrive !
And report bugs says pixmap error !
Perhaps same bug.

lucid A2 on 32 bit vsta
had firefox open on gnome - so didn't notice what happened

It happened when I clicked the "Appearance" entry in "System Settings."

Forgot to mention I am running 32-bit Lucid, fully updated as of right now (and having rebooted since the update).

Just hit it again with kwin when I tried to apply my display settings.

Upstream has a patch they've committed against trunk. In cooperation with upstream, I have been testing the patch for the better part of the week. It fixes the bug and has no known regressions. We definitely should get this in for 10.04.

Patch committed to bzr for the next packaging release.

This bug was fixed in the package kde4libs - 4:4.4.1-0ubuntu3

---------------
kde4libs (4:4.4.1-0ubuntu3) lucid; urgency=low

  [ Jonathan Thomas ]
  * Add kubuntu_72_kpixmapcache_discard_fix.diff to fix various crashes while
    toggling compositing or changing Plasma themes (LP: #321281)
    - Can be dropped in KDE 4.4.2
  * Add kubuntu_73_silence_kdebug.diff to fix applications being verbose when
    KDebug isn't enabled (LP: #540944)
    - Can be dropped in KDE 4.4.2

  [ Scott Kitterman ]
  * Manually remove mimetypes/kde.xml.podir that somehow crept into the
    diff.gz

I'd just recommend updating to Lucid or higher at this point.
