- Not always reproducible

apper (0.8.1) on KDE Platform 4.10.5 using Qt 4.8.4

- What I was doing when the application crashed: I opened apper and wanted to check the applications listed under the Applications category.  I double clicked the Applications category icon by mistake instead of a single click, then almost immediately Apper crashes and the bug report message appears.

This crash was reproducable by again opening Apper and again double clicking the Applications category icon.

I then tried each of the other category icons.  Double clicking on some of these other categories also cause Apper to crash. In particular double click on "Base System",  "Development", "Servers", or "Applications" all cause Apper to crash and then the bug report message.

Closer examination shows that It appears if you double click the top level categories show above, Apper begins to open the next window in sequence on the first mouse click and then the second click actually executes as the second window opens, then if the mouse happens to be resting on another icon in that second window as the second click actually executes. that then causes Apper to crash.

Would appear to be a timing issue, ie selecting category then sub category too fast causes the crash to happen.  Single clicks so far cause no issues in Apper for me.


- Unusual behavior I noticed:  System seems to be slow at picking up if there are any updates to be had, so far the auto update process hasn't notified me of updates, I instead have to manually open Apper and look for updates.
Some programs though installed are not showing as installed in Apper.  For example Blender is installed and functioning, but Apper doesn't show it as installed if I search for it.  It instead gives option to install.

Note I upgraded from 17 to 19 via Fedum, so perhaps the upgrade has partly failed?
