Comment # 4 on bug 868702 from Tom���� Chv��tal

This seem to be sorted  out on leap/Tumbleweed.

Even tho it still tries to open the swp in the folder where it works it seem to
fallback and not store garbage. Could you please test it too and reopen if it
still happens?

scarabeus@bugaboo: /usr/local/bin $ kate -n test                                
Attempted to re-run an already running session.                                 
QIODevice::write (QFile, "/usr/local/bin/.test.kate-swp"): device not open

Note: it still breaks the back/forward buttons so it should be fixed by
upstream to use /tmp/kde-<user>/ for file caches.
