Problem description: When there's something playing, or has already played with flash content (like youtube videos), and then I attempt to search for text in a page and that text is NOT found, the browser crashes (segfault).
I found 2 solutions to this, one of them seems more of a workaround rather than a solution, and the real problem seems to be coming from Adobe's Flash plugin for Linux (they just can never get it right...).
- Turn off search sound: open a tab and in the address type: about:config
look for sound and then disable: accessibility.typeaheadfind.enablesound by double clicking it, then restart your browser.
- Use nspluginwrapper along with Adobe's libflash package. Whether the search sound is enabled or disabled, this should work just fine.
