Similar problem has been detected: This time visited the same YouTube page, but with Flash plugin completely disabled (so we know for sure it's not related at all). reporter: libreport-2.6.4 backtrace_rating: 4 cmdline: /usr/lib64/seamonkey/seamonkey crash_function: nsProfileLock::FatalSignalHandler executable: /usr/lib64/seamonkey/seamonkey global_pid: 17504 kernel: 4.4.6-300.fc23.x86_64 package: seamonkey-2.40-1.fc23 reason: seamonkey killed by SIGSEGV runlevel: N 5 type: CCpp uid: 1000 And the video it's crashed on: https://www.youtube.com/watch?v=gT5tGHTu-Ws - perhaps some specific codec on that one. Please, check it on the clean profile. According to backtrace, looks like another "profile lock" issue... *** This bug has been marked as a duplicate of bug 1310418 *** That bug is not public so can't say whatever findings you have there. So I'll ask here: How does "mozilla::MediaDataDecoder::DecoderFailureReason" signify a "profile lock" issue? Unless anything that is caught by "FatalSignalHandler" from the "nsProfileLock" object is a "profile lock" issue? I'm probably not understanding the reference you were making, but that's only because there seems to be no other public bug except mine... So I'm reopening because I found and want to publish a work-around for other affected users. It also allows free reproducibility, which should point right to the cause. So a work-around, and frankly, for me, a complete solution is: sed -i '/gmp/d' .mozilla/seamonkey/*.default/prefs.js On all my systems I had media.fragmented-mp4.gmp.enabled set to true, and that single preference either makes SeaMonkey crash on certain videos. All my SeaMonkeys have been upgraded for years, the freshest profile was created under Fedora 18, so I'm not sure if I have set the gmp preferences myself or were they the default in the gmp-openh264 times. But fact is, SeaMonkey 2.39 never crashed with those gmp settings enabled, and 2.40 crashes or hangs all the time. I hope someone else finds this finding helpful, as it took me half a day to find! (including a false lead with removing youtube.com cookies from cookies.sqlite which also helped but only for a single session ;)) > SeaMonkey 2.39 never crashed with those gmp settings enabled, and 2.40 crashes or hangs all the time. Since 2.40, SeaMonkey starts to use ffmpeg libraries directly. Previously, gstreamer was used to play media without using flash-plugin (support of gstreamer goes to be removed after 2.42 ...). Probably it is a reason why the *gmp* settings did not affect before, since *fragmented-mp4* are related mostly to ffmpeg. > I'm not sure if I have set the gmp preferences myself Should be off by default. Check it in "about:config" -- if it is highlighted (by bold), then it is not default. If so, please, close this as "notabug" and change the bug summary to reflect the actual issue (for other people who might be affected by it). Even if I enabled that myself (perhaps I was just blindly setting all of *mp4* to true in the "old times"), it's still a crash and a 2.40 regression in my eyes :) It seems that *fragmented-mp4* will go away in the next release at all :) |
