corrupt icon file (4.27 KB, image/png) 2007-09-12 17:24 UTC, Sven Arvidsson	Details

Description Sven Arvidsson 2007-09-12 17:24:05 UTC

[ Forwarded from http://bugs.debian.org/427406 ]

metacity-dialog hangs, and no keyboard or mouse input is possible if metacity is started with a corrupt icon cache.

Steps to reproduce:

      * Drop the corrupt icon file (attached) in /usr/share/icons/hicolor
      * Generate the icon cache using GTK+ 2.10 
      * Restart metacity and invoke metacity-dialog.

This only happens with GTK+ 2.10, in 2.11 it refuses to create the cache, complaining about a bad image index. 

The corrupt icon came from an old version of autopackage, they have since replaced it, http://trac.autopackage.org/ticket/31

I attached the the process after the hang, and got a limited backtrace:

Comment 2 Havoc Pennington 2007-09-12 18:47:31 UTC

Seems unlikely to be metacity-specific, though metacity-dialog using gtk_dialog_run may trigger it while other apps don't. Reassigning to gtk since no code I know of in metacity should care about the icon cache directly.

Comment 3 Johan (not receiving bugmail) Dahlin 2008-03-02 17:26:14 UTC

The stack trace is corrupt, there's not a lot we can do.

Sven: can you still reproduce? If so, please send in a new stack trace after you installed the dbg/dbgsym packages for glib/gtk.

Comment 4 Sven Arvidsson 2008-03-05 21:42:38 UTC

Thanks for reminding me. No, I can not reproduce it with GTK+ 2.12.8 (still using 2.10 to generate the icon cache) and Metacity 2.23. I guess the bug can be closed.
