Okular crashes on 16 bit display

[Hans-Joachim Baader]

Binary package hint: kdegraphics

Okular crashes on loading a document, eg. okular /usr/share/doc/foo2zjs/manual.pdf

This only seems to happen on 16 bit displays. To reproduce, you need to start X with -depth 16 or so.

I'v only tested Kubuntu 10.10, but cannot remember such a problem in earlier versions.

Version 4.5.1-0ubuntu3

Hi there!

Thanks for reporting this bug! Your bug seems to be a problem with the KDE program itself, and not with our KDE packages. While we appreciate your issue, it would be better if it was tracked at https://bugs.kde.org, so that the KDE developers can deal with this speedily and have direct communication with you as the reporter for more effective debugging.

Thanks!
