No trace at all (system told me that the trace was unusable) but some additional steps to help you to reproduce the bug : Here are the differents points I noticed : 1) A very small amount of themes install correctly. These themes are very slower to download (bigger ?) Themes tested and working for me are Tangoish KDE and ACUN Simgeleri. Tangoish took around 20 seconds and ACUN more than one minute. When these themes are installed, the button changes to Uninstall. When we click on Uninstall, these buttons change very quickly back to Install. 2) The themes that don't install correctly are very fast to download (between 1 and 4 seconds), and for some, we don't even see the progress bar running (only the busy cursor). When these themes are (normally) installed, the button keeps to be Install. When we click on them, these buttons change very quickly back to Install (I mean that we see exactely the same behaviour than point 1, the busy cursor appears but very quickly, tens of a second) For odd clicks, the (install ?) time is always greater than the even clicks (uninstall ?), but buttons remain the same. 3) To make the system crash, follow these steps (no need to click quickly as told in previous comments) : a) click to install on a theme from point 2 (the busy cursor is displayed for more than 1 second and button remains Install) b) click on the same Install button (lightspeed busy cursor, button always Install) c) click on install again (and again the busy cursor is displayed for more than one second and button remains Install) [You can repeat steps b and c, but you must end with step c to make the system crash. Terminating with step b won't make the system crashing] d) click on close The systemsettings crashes immediately.
Created attachment 31443 [details] Crash backtrace
All themes crash for me. Progress bar d'ont change, same if I re click on install.
