compiz crashed with SIGSEGV in pango_renderer_draw_layout() from ? from nux::StaticCairoText::Impl::DrawText() from nux::StaticCairoText::Impl::UpdateTexture()

[Sasa Paporovic]

Compiz crashed right after login in unity.

That has no specific user action. It is the first time I observe this.

The login works in all other cases normal without any compiz crasher.

Very close to bug 977891 I think. But that one is expired.

[Sasa Paporovic (melchiaros)]

What is with apport retrace? Has it failed?

[Daniel van Vugt (vanvugt)]

Not sure. If you can reproduce the bug again please log a new report for it. Maybe better luck 2nd time.

As part of the big bug clear up for 16.04 LTS I am marking this bug as Wont Fix. These types of crasher are better handled by errors.ubutnu.com which can collate similar crash reports to help us identify persitent bugs rather than one-off crashes. Sorry we are not able to help with this specific issue. If you are still experiencing this crash, please re-open the bug and add the tag “desktop-bugscrub-reopen”. See https://wiki.ubuntu.com/BigDesktopBugScrub for more information.
