kpat uses 100% CPU for a while when selecting game type

[Graham Menhennitt]

Binary package hint: kde4libs

I've done a fresh install of Kubuntu Jaunty on a Dell Inspiron 6400 notebook. I then added kpat (KDE patience card games) via KPackageKit. I start kpat and it asks for the game type (shows the 4 x 3 grid of the games). When I click on one of the games to select it, kpat starts using 100% of the CPU time. It stays like this for between 15 and 40 seconds. Eventually, it deals the cards for the game and the CPU usage drops to normal.

I was wrong above. The problem happens whenever it deals a new hand - not just the first time on starting the program.

Sorry, it seems this was my mistake. Please close this as "not a bug".

For the benefit of anybody who makes the same mistake, it appears that it happens if there are files in /var/tmp/kdecache-<username> that are not owned by <username>. I suggest removing this directory and letting it be recreated.

I had changed my UID (to match my UID on a NFS server). I changed the ownership of all files in my home directory to match the new UID and then rebooted. But I didn't realise that there were files elsewhere that persisted across reboots.
