Bug Description

impish with updated packages. I find this entry in /var/log/syslog:

Aug 8 00:22:28 gunnar-ubuntu-dev kernel: [ 2710.184084] scribus[16001]: segfault at 0 ip 00007f526c9e5c74 sp 00007ffe750286d0 error 4 in libQt5Core.so.5.15.2[7f526c923000+30f000]

But scribus 1.5.7+dfsg-1 runs fine on Debian testing with the same version (5.15.2+dfsg-9) of the libqt5core5a package.

Rebuilt scribus (in impish PPA), but it didn't make a difference.

@Mattia: I run apport-collect, but it seems not to include a traceback.

Please note that the segfault is easily reproducible on impish.

Thanks to Dmitry Shachnev (mitya57), he figured out the likely root cause for this, and Rik Mills then found a workaround/solution (disable LTO).

I reported the bug upstream at https://bugs.scribus.net/view.php?id=16637 and I'm uploading a -4 with LTO disabled to fix the issue for now in the distribution.

This bug was fixed in the package scribus - 1.5.7+dfsg-4

---------------
scribus (1.5.7+dfsg-4) unstable; urgency=medium

  * Update the harfbuzz-subset patch with another fix.
  * Set upstream metadata fields: Bug-Database and Bug-Submit.
  * Remove now unneeded dh-exec-subst-unknown-variable lintian override.
  * Override the unusual-interpreter lintian warnings.
  * d/rules: Disable LTO, as it causes segfaults on startup. LP: #1939213
    Thanks to mitya57 for the debugging and RikMills for finding a solution.
