Status: RESOLVED DUPLICATE of bug 1456327

(Release Engineering :: Release Automation: Other, defect)

Refreshed the Snap Beta channel from 60.0b14-2 revision 80 to 60.0b15-1 revision 81 and now it crashes immediately on start.

Some highlights from the crash log:

Revision 81 has a new file "bindtextdomain.so" which is referenced in every backtrace of the crash.

Thanks for the report! The backtrace is different from the one in bug 1456327, but the logs are identical. I don't think something changed in bindtextdomain. That's a library we imported in tree in bug 724531. It hasn't changed since then[1]

Let's track the resolution in bug 1456327.

I don't think this is really a duplicate.  This is an interesting backtrace, considering our new bindtextdomain that was introduced.  However, I'm not seeing crashes in other snaps yet.

Alright, reopening bug. Thank you for the context! I see bindtextdomain was changed 3 days ago[1]. I also see the `mkdir -p` calls were moved from launcher-specific[2] to desktop-exports[3]. Does it change the steps at which the folders are created? Can I target a different revision of desktop-gtk3 in the manifest? That would allow to test out b15 without these changes.

I confirm the start up crash is caused by the same root cause as bug 1456327. See bug 1456327 comment 12 for more detail.s
