Application: rekonq (0.7.92) KDE Platform Version: 4.7.1 (4.7.1) Qt Version: 4.7.2 Operating System: Linux 2.6.38-11-generic-phc x86_64 Distribution: Ubuntu 11.04 -- Information about the crash: - What I was doing when the application crashed: After I compiled okularplugin (an okular plugin for firefox that allows text search in pdf files. https://github.com/jeremysanders/okularplugin#readme) and copied libokularplugin.so to $HOME/.mozilla/plugins, rekonq crashed whenever I tried to open a pdf file. Somehow rekonq is aware of the firefox plugins and doesn't like this one. This in my opinion should not happen, what does rekonq have to do with firefox plugins at all? - Custom settings of the application: I use the okularplugin in firefox because it is the only way I know to open and search text in pdf files in a browser (as far as I know search text in pdf files is not supported in rekonq right now, that's why I use firefox and this plugin). The crash can be reproduced every time. -- Backtrace: Application: rekonq (rekonq), signal: Segmentation fault [Current thread is 1 (Thread 0x7fd8a8d9e780 (LWP 32689))] Thread 4 (Thread 0x7fd889b66700 (LWP 32690)): #0 0x00007fd8a1b29bac in pthread_cond_wait@@GLIBC_2.3.2 () from /lib/x86_64-linux-gnu/libpthread.so.0 #1 0x00007fd8a7985832 in ??

I filled a bug also in launchpad: https://bugs.launchpad.net/ubuntu/+source/rekonq/+bug/865729
by the way, I tried to make a better backtrace but I couldn't install required kubuntu packages

Just for clearness, okularplugin is just one of the plugin supporting NPAPI specs. You call it a "firefox" plugin, because you probably use firefox with it, but it should work in firefox, chrome, opera, rekonq, konqueror... the same rules with flash and so on. > I use the okularplugin in firefox because it is the only way I know to open and > search text in pdf files in a browser (as far as I know search text in pdf > files is not supported in rekonq right now, that's why I use firefox and this > plugin).

I didn't know that, thanks for telling :) However, if rekonq uses some plugins from firefox's folders, it's possible that they don't behave properly and interfere, as in this case, making rekonq to crash. Shouldn't it be an specific folder for rekonq or a way to specify which of the plugins in firefox's folders you really want to use? > Just CTRL + F (or find from tools menu) inside a pdf opened inside rekonq view. This is the way it works also in firefox. With default kpartsplugin in okular within rekonq (and firefox), ctrl+f opens browser's search box, so it's impossible to search inside the pdf file (at least in my case, does it work for you?) With okularplugin, ctrl+f in firefox works perfectly with the above procedure. Would be great to have okularplugin working also in rekonq (or a kpartsplugin that alllows the text search), so I would not have to use firefox for this purpose. By the way, thanks for your rapid response! And please don't take my point wrong, I love rekonq and would like to use it also to search inside pdf files :)
I just wanted to add that I am willing to help to have okularplugin working properly also in rekonq, so if you would like me to test something or collaborate in any way, please tell me... At this time I don't know much about rekonq or okularplugin/kpartsplugin codes, but I think there is some few people out there that would really like being able to search in their pdfs while in rekonq. This would be a very nice feature to have, and if you would guide me a bit, I could try to work on it!
This crash does not come from our code, as you can see in the backtrace.
