I now remember I also did a "Trim Edges" then "Undo", and this may be
the cause of the crash, since "Trim Edges" on

  http://www.vinc17.org/test/cwt.png

yields random images.

Bug#374631: imagemagick: display segfaults after crop's + undo

2006-06-20 Thread Vincent Lefevre 
Package: imagemagick
Version: 7:6.2.4.5.dfsg1-0.9
Severity: important

With "display", I did several crop's on a PNG image. The last one only
reduced the height of the image and the resulting image was something
completely different. So, I did an "undo", but display crashed:
