Title:
wxRuby crashes with segmentation fault in pixman_image_composite32
I am also severely affected by this bug in Natty and desperately looking
at least for a workaround. Below there is a stack trace of my simple
gtk-application crashing in pixman_image_composite32() - I'm not sure if
that helps. I would really appreciate a fix of libpixman-1-0 for Natty.

I can confirm David Beswick's findings and add a few details.
I experience this bug with versions 0.20.2, 0.22.0 and 0.23.1 (from today's git
master). Please have a look at my attached gdb trace (pixman git master on

I re-tested this in Natty and it still happened. But going off the
suggestion in that bug, I recompiled wxruby while excluding GLCanvas,
and I found the problem doesn't occur, wxruby works fine. Maybe the
issue is in Mesa as the bug suggests.

I've found out what causes this bug; I found this bug not in wxRuby, but
in wxLua---but its the same bug, using pixman 0.20.0 seems to fix it.
The offending commit (after trying each commit from 0.20.0 to 0.20.2 is:
Hi, have you had a chance to test if this bug is still present in
natty?

apport-collect bug-number

natty. (It is

This is a strange one, I'm not sure exactly where the fault lies.
Basically, performing almost any operation in a wxRuby app causes a
crash in pixman_image_composite32. This crash doesn't occur when running
I've been experiencing the same problems on an Ubuntu as well as on an
Arch Linux box. With pixman 0.20.0 installed, everything works fine (on
Arch), but the next release 0.20.2 causes wxRuby to crash.
Oh and this one:
2. Install the wxWidgets gem: sudo gem1.9.1 install wxruby
will crash
