Hm, yes. Here's a bit of a stacktrace with line numbers:

Still occuring in 1.6.0, though I'm a bit confused as the website still has
latest as RC1 (1.5.92)

I don't want to sound like a whiner, but shouldn't something this basic and
easily reproducable be considered a blocker on even a release candidate, never
mind a final release?

1.6.0 is still not release :) but no, it's not easily reproductible doesn't
mean blocker.

> krita --version
Qt: 3.3.6
KDE: 3.5.4 "release 88.1"
Krita: 1.6.0

OK, so someone, somewhere is obviously jumping the gun.

Maybe I worded it wrong. It was more the outcome, and basic-ness of the operation that led to it, that I thought would make it a blocker. An application crash on something as mundane as pasting from the clipboard into a group layer would be in definate need of fixing if I had anything to do with it. Unfortunately, I don't have anything to do with it bar the reporting, so I'll slink back to my corner and be quiet now.

'pologies for the disturbance, guv'nor, won't 'appen again. <doffs cap>

I think there was some grammar missing in Cyrille's reply... The problem with
this bug is that it isn't easy to solve: I was able to reproduce it myself, but
the place where it seems to happen is really weird.

And since Cyrille is really busy doing the 1.6 release today, and I'm working
really hard on 2.0 (which doesn't have the code where the crash happens
anymore), we had to -- reluctantly -- decide we couldn't fix it in time of the
release. Which doesn't mean that your clear and helpful bug-reports aren't
appreciated!
