Bug 550524

Created attachment 380341 [details]
File: backtrace

I have run all the debuginfo-install commands the abrtd-panel-applet has suggested:

  512  debuginfo-install firefox
  523  debuginfo-install midori
  524  debuginfo-install galeon
  530  debuginfo-install google-chrome-beta

Those all www-browsers crash on any flash-content (at least youtube.com videos).

I do not know if it helps to send all those crashes from different www-browsers.
It seems (to me) the error would be in Adobe's libflashplayer.so
The same www-clients and the same Adobe flash-plugin works on this other single CPU-x86_64-machine. The crashing one is dual-x86_64-cpu.

If gnash-plugin is used instead, no crash (but gnash does not support all flash content)

"Missing separate debuginfos, use: debuginfo-install libcurl-7.19.7-3.fc11.x86_64 libflashsupport-000-0.5.svn20070904.x86_64"
Those cannot be found. Adobe would need to give debuginfo for libflashplayer.so

Same kind of backtrace with the same URI with firefox in safe-mode here:

Misc info about the platform: (the crash seems to happen when libflashplayer.so is trying to do something with PCM sound.)

Sorry for the delayed response.
This is obviously related to the flash plugin, which we can't really fix.
I have the flash plugin working here on testing setup without such problems, perhaps you can upgrade to its latest version and try again. In any case this should be reported to Adobe.
