Fixed this by cleaning up my ~/.mozilla directory. It contained some stale files from older plugin installations which firefox did not use. (After installation of package flashplugin-nonfree firefox used the plugins in /usr/lib/flashplugin-nonfree instead.)
Actually I didn't trace which file was the real cause of the problem but the following steps fixed it: aptitude install flashplugin-nonfree konqueror-nsplugins cd ~/.mozilla rm pluginreg.dat plugins/* cd plugins/ ln -s /usr/lib/flashplugin-nonfree/libflashplayer.so . (You might want to make backups of the files before removing them.) I guess that it's possible to make konqueror look into the same directories as firefox. Perhaps it's possible to implement a general fix in the nspluginviewer package in this way. -- nspluginviewer crashes badly on flashplayer https://bugs.launchpad.net/bugs/16502 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
