Bug Description

Steps to reproduce:

1. Open a windows that you know it takes a little while to close (example.: Google Chrome with 8 tabs)

3. When the window finally gets closed and the launcher icon dissapear, the quicklist stays as “orphan” and Unity crashes.

Thanks for your report.

I can reproduce it with the steps indicated. Looks like a nux bug according to the trace. Moving there and setting to triaged/high.

I am not sure this bug still applies. Please re-test.
Also, is there a way to reproduce this bug reliably without involving the user action speed?

I've tried to reproduce, but it's actually very tricky. I think it's worth keeping around as a reminder, but that would be a rare crasher for me.
Please reopen if you can get a backtrace with symbols, or an apport retrace of the issue.

Thanks

@dbarth, i think that mounting a usb pen drive, opening its launcher icon quicklist and removing manually the pen drive should crash unity.

@andyrock: can you generate a stack trace of the error? that would help narrow down the issue and know where to fix in the code. thanks

backtrace.log Edit (3.6 KiB, text/plain)

This is my backtrace.

An easy way to get unity crashing is to:

- Add some .desktop files to ~/.local/share/applications
- Drag them to the launcher to make them show there
- Run something like sleep 5 && ~/.local/share/applications/desktop_file.desktop /tmp
- Open the quicklist
- Wait for crash (sigh!)

I should have fixed this in my branch lp:~3v1n0/unity/quicklist-hide-fix (commit 1502, http://bazaar.launchpad.net/~3v1n0/unity/quicklist-hide-fix/revision/1502)

Basically it seems related to compiz or Nux since after clicking on a quicklist, we're waiting for a click outside its area to hide that.
If the quicklist is forced to close this can't happen anymore, so we need to hide it and stop monitoring for events before removing the launcher icon.
