A little more info on this. Updated mythplugins to r21981. loads and does not crash. Can not see the search box (image attached). Clicking on images/shopping and typing in a search term does not crash. Clicking on videos segfaults, browsing to - segfaults, segfaults.

Attached another backtrace from r21981 and the segfault from

Tried MythCenter? and ProjectGrayhem? as themes.

Figured this out.

Considering gdb did not show anything I found useful, I used strace. Strace showed mythfrontend bailing once it hunted for plugins in the 15 or so predefined plugin directories.

/usr/lib64/mozilla/plugins is the only directory system wide that holds browser plugins, and has 4 files

Removed them all, added back one by one. The problem plugin was (Jave JRE), which is a soft link to /usr/lib64/java/lib/amd64/ JRE does work in konq and Firefox. Removing the link and copying fixes the problem for, but not google-videos.

Perhaps mythbrowser is not compatible with 64bit JRE?

I don't see anything to suggest mythbrowser is at fault the crash is within qtwebkit and MythBrowser? doesn't have anything to do with scanning for plugins that's all handled by qtwebkit. Like you say it could be a buggy plugin.
