[Bug 242007] [NEW] Adobe Flash with libflashsupport frequently crashes Firefox when viewing SWFs (e.g., on YouTube)

[Tristan Schmelcher]

Public bug reported:

Binary package hint: flashplugin-nonfree

I have a Dell XPS M1710 laptop running pure up-to-date Ubuntu Hardy
32-bit. When libflashsupport is installed, viewing videos on YouTube
frequently crashes Firefox just as the video is loading. Navigating from
one video to another via the list on the right will very quickly repro
this bug. When libflashsupport is NOT installed this bug does NOT occur.
The crash is a segmentation fault, but for some reason there is no crash
file for me in /var/crash and apport does not get triggered. Instead I
am attaching the output from a gdb session, which contains a full
backtrace.

This is probably the same as bugs 207228, 238838, and more, but I see
from the comments on those that we're not supposed to confirm other
people's crash bugs.
