Description From boud valdyas org 2006-09-22 15:12:13

Version:            (using KDE KDE 3.5.4)
Installed from:    Ubuntu Packages

I get the following crash when using the magic wand/select contiguous tool on the roof part of the attached image. Sometimes one click is enough, sometimes more clicks are needed.

#6  0xb5de1d09 in KisBasicU8HistogramProducer::addRegionToBin (
    this=0x89860e8, 
    pixels=0xa6fc2f10 "\024\021\023

Created an attachment (id=17878) [details]
image with which I can crash Krita

You may want to crop until just the building with the two towers is left.

------- Comment #3 From Bart Coppens 2006-09-22 17:24:29 -------

SVN commit 587382 by coppens:

Fix a crash where the histogram docker would try to fetch selectedness outside of the consecutive area of the selection (but inside the consecutive area of the actual iterator). This shouldn't have happened because the comment of selectionMask() says it shouldn't:
'this is guaranteed to have the same number of consecutive pixels that the iterator has at a given point'

Seems to be needed after the fix for the difference between selection and actual conseqpixels. Seems a bit weird but doesn't loop infinitely anymore.
