Description of problem: When using X terminals having only 8 bit color depth, firefox crashes after the upgrade to Firefox 3. Version-Release number of selected component (if applicable): firefox-3.0.6-1.el4 evolution28-cairo-1.2.4-6.el4 How reproducible: Every time Steps to Reproduce: 1.Log in on a display with 8 bit color depth, or start a vncserver with option "-depth 8". 2.If applicable: connect to the vncserver with vncviewer 3.Start firefox Actual results: A crash with this output: Error: Cairo does not yet support the requested image format: Depth: 8 Alpha mask: 0x00000000 Red mask: 0x00000000 Green mask: 0x00000000 Blue mask: 0x00000000 Please file an enhacement request (quoting the above) at: http://bugs.freedesktop.org/enter_bug.cgi?product=cairo firefox-bin: cairo-image-surface.c:155: _cairo_format_from_pixman_format: Försäkran "NOT_REACHED" falsk. /usr/lib64/firefox-3.0.6/run-mozilla.sh: line 131: 21557 Avbruten (SIGABRT) (core dumped) "$prog" ${1+"$@"} Exit 134 Expected results: A firefox browser window should come up.
caillon, can you take a look at this?
It's because firefox tries to use 8bpp surfaces internally - but this is not supported by cairo image/pixman. Can check if it's possible to run firefox internally in 32-bit depth.
Anyway, not sure it's worth to deal with it. Seems to be cause by cairo version used in rhel-5 (and evolution28) - currently whole GTK crashes when RHEL-5 desktop is run in 8 bit color depth.
To avoid causing duplicate efforts, I want to mention that there is a service request number 1896950 about the "business side" of this problem.
