Ah, libflashplayer.so appears in the stack trace, so a likely culprit is my Adobe plugin. (But after removing libflash0c2, libflash-swfplayer, and libflash-mozplugin, I can't reproduce the crash. Perhaps these conflict with the Adobe plugin. Damned Flash.)
Epiphany-browser still has the following bug, IMHO: it allows a buggy plugin to crash the epiphany process. Could it be made more robust against rogue plugins? -- [Feisty] Crash displaying pages in the Amazon Online Reader https://launchpad.net/bugs/78441 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
