By default, Bugzilla does not search the list of RESOLVED bugs.
You can force it to do so by putting the upper-case word ALL in front of your search query, e.g.: ALL tdelibs
We recommend searching for bugs this way, as you may discover that your bug has already been resolved and fixed in a later release.

Drkonqui dump of the nspluginviewer crash

I'm running Trinity 3.5.12 for stability, but I patched and locally rebuilt kdebase-trinity by cherry-picking the nspluginviewer patch from r1224648, so that I could use a more modern version of Adobe Flash.  Hence I've reported this against 3.5.13 as the code appears identical, apart from the recent TQt changes.

This patch works for Adobe Flash up to 10.2 (currently using version 10.2.152.27), however nspluginviewer crashes when used with Adobe Flash plugin 10.3 (now current) or 11.0 (beta).

Attached is a backtrace.  The crash appears to happen as soon as the plugin is loaded, before playing anything.  Web site involved was some random Youtube video ( http://www.youtube.com/watch?v=2gGTrz_JTfo&NR=1 ) but this is reproducible anywhere.

Implement NSAPI RESPONSE_HEADERS in nsplugin.

Cherry picked from KDE4, acknowledgements to Maksim Orlovich for the fix.

Comment 3 Nick Leverton 2011-09-26 04:50:53 CDT

Fixed in KDE4 so I've adapted their fix for Trinity.  Allows nspluginviewer to work on youtube.com with Flash 10.3 and 11.  I'd welcome review by someone who actually knows Qt programming :)

Comment 4 Timothy Pearson 2011-09-26 13:43:03 CDT

Patch looks sane and compiles correctly.  Committed to SVN in revision 1255714.

Thanks for working on this!
