Reproducible: Didn't try

Comment 2 Dmitry Kazakov 2010-08-20 17:50:30 UTC 
There is an infinite loop in KisPaintOp::paintLine, because 'double sp = savedDist.spacing;' returns *zero*, so no incrementing happens.
Comment 3 Kubuntiac 2010-08-22 17:08:13 UTC 
Confirmed, using:
Krita revision 1166713
Kubuntu 10.04 32bit
KDE 4.5
QT 4.7.0 beta 2
Comment 4 George Goldberg 2010-08-22 23:11:05 UTC 
Confirmed. I get a deadlock. Debian unstable + KDE ~4.5 + krita trunk + Intel graphics
Comment 5 Halla Rempt 2010-08-30 16:56:07 UTC 
Should be easy to fix then.
Comment 6 pentalis 2010-09-04 07:22:15 UTC 
SVN commit 1171519 fixed this.
Comment 7 Halla Rempt 2010-09-04 08:44:33 UTC 
Feel free to close :-)
