[Digikam-devel] Bug#693826: digikam crashes when stitching panoramic images

[Markus Geimer]

Package: digikam
Version: 4:2.6.0-1+b1
Severity: important

Dear Maintainer,

digikam crashes whenever I try to stitch panoramic images. After selecting
two or more images in the thumbnail view and choosing "Tools -> Stitch
images into a panorama...", the wizard dialog opens. Pressing the "Next"
button three times starts the image pre-processing, but digikam crashes
after a few seconds. This behavior is reproducible.

According to the stack trace, the crash happens within the boost spirit
parser:

According to http://mail.kde.org/pipermail/digikam-users/2012-July/016621.html
this parsing code was unintentionally included in the release, i.e., patching
this issue should be straightforward.
