Crash report file
@Hugo: please have a look at the crash trace. The crash seems to go through Oxygen size grip. mmm. I guess I'll need to log-in into kwin5 (tm) directly to try reproduce. I cannot reproduce (last time I checked at least) when lauching kwin from kf5 manually (--replace) Also, the crash happens in kdecoration (when accessed via sizegrip). Dangling pointer ? In any case, I'll investigate when I am home. Maybe this makes things easier to debug... I just discovered that I can trigger the bug also whenever I'm starting kmix manually. To reproduce: quit kmix, run kmix. I'll attach the backtrace immediately. Created attachment 89420 [details]
Backtrace when starting KMix
Question: you are running with window-borders = None. Correct ? If yes as a temporary fix you can probably set it to smthing larger (no side borders, or tiny) @Hugo: Crazy. With tiny borders it's not crashing anymore. Thanks for the hint. Git commit 96a74a12570a9f6c65fb43a1416a020b4ae1c4f7 by Hugo Pereira Da Costa. Committed on 03/11/2014 at 16:10. Pushed by hpereiradacosta into branch 'master'. Added WeakPointer typedef to oxygendecorationdefines to allow compilation against both KDE4 and KF5 Use WeakPointer<Client> inside Oxygen::SizeGrip to keep track of client deletion and avoid crash.

(using again 'no borders') ? Here I could reproduce (and cure) the kmix crash I guess some paint events arrived to the size-grip after its parent decoration was destroyed. (the size grip is not destroyed with the client because it is created as a top level window) Hi Hugo, how should I double-check? I'm not running plasma from git but I use the kubuntu next ppa. I don't really want to compile from source. Is there any other way in which I can help you? Cheers, Stefan. @Stefan Nope, apart from waiting for next ubuntu update. Compiling oxygen only should not be too much of a big deal though (its a small package), provided that you have the right "dev" packages installed (the header and .so shared libraries. |
