Can I get an older version(s) of Calligra master from git? I need one just before 09/23/2011, for... some experiments.

Yes, sure. The easiest (for me...) way would be to go to your source checkout and do a "git log" command. Go through the messages until you find a likely commit. In your case, you probably want to go back to before the merge of the strokes framework, so I'd do a

"git checkout 6d6cfcd383fdabcced059bd7d5f994d792cec554"

which checks out a version right before this commit:

Merge remote branch 'origin/master' into krita_strokes_framework_kazakov

I had to revert a part of ef3277a2bd7dd0b9454114d1562b633dff47c86e,
because caused a conflict. It's destination code has been moved to
a different class (KisIndirectPaintingSupport) and it should be ported
to this class.

Conflicts:
krita/ui/tool/kis_tool_freehand.cc
krita/ui/tool/kis_tool_freehand.h

And then make and install as usual.

Thanks!

...and excuse me for a stupid questions. (it's because I'm new in Linux)

I don't think the question was stupid -- on the contrary!

By the way... that "hangup bug" is fixed (as I think):

A patch that probably fixes crashes during painting

I'm not sure this is the real cause of hangups/crashes. So revert it
if you still get crashes.

I have tried now git version ab73d55b..., and, seems to me, no hangs after draw a lot.

Thanks for the confirmation! We're still working on a proper fix, this was just a really nasty hack to get things working again.
