From Bugzilla Helper: User-Agent: Mozilla/5.0 Galeon/1.2.0 (X11; Linux i686; U;) Gecko/20020509 Description of problem: After receiving mozilla 0.9.9-12.7.2 via up2date today, both mozilla and galeon frequently crash in a VNC session. The normal X-server on this box does not have this problem. One of the urls that shows this problem is info.nld.chello.nl Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Inside a VNC session to the local machine, start galeon 2. surf to info.nld.chello.nl 3. At this point, the following may be displayed: [konijn@banaan konijn]$ galeon Message: Successfully registered `OAFIID:GNOME_Galeon_Automation' IDN support disabled escape UTF-8 enabled Gdk-ERROR **: BadMatch (invalid parameter attributes) serial 47 error_code 8 request_code 129 minor_code 3 [konijn@banaan konijn]$ 4. Trying to restore the session gives a seg fault. 5. The segfault also happens frequently with other sites, but if I try to reproduce that now this bug report crashes too... 6. Visiting the same site in the native X-server shows no problem. Actual Results: Sometimes crash, sometimes gdk error Expected Results: Displayed page. Additional info: I'll attach xdpyinfo for VNC and normal X-server later.

Are these pages with flash?
That seems to be it. info.nld.chello.nl works on a normal X display, but crashes in vnc. This behaviour remained the same after I stripped the page to just the flash embedding (see attachment). After removing libflashplayer.so, no more crash in vnc. (and the annoying movie is gone as well.) The flash version: $ rpm -qf /usr/lib/netscape/plugins/libflashplayer.so netscape-common-4.78-2 $

It's a known bug to which there is no fix. :( http://bugzilla.mozilla.org/show_bug.cgi?id=58937
