After finding this bug I try to find the file pulse.mng and dolphin says that it requires an additional complement to decode the file. Looking that complement makes no results. Using Muon Package Manager and looking for Multiple Image Network Graphics I found that libmng2 is installed, and actually a could open the file with ImageMagick (it does not handle the animation, but using View > Refresh I can have an Idea of the use of the .png files).
Renaming the file /usr/share/kde4/apps/kdbg/icons/hicolor/22x22/actions/pulse.mng to .../pulse.mngBAK did correct the problem. However, I saw a new funny little problem: the icon of the program at the launcher was lost. I'm pretty sure that the proper icon was in use before. So, I had to correct that "by hand". -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1311893 Title: kdbg does not start after upgrading to Trusty To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/kdbg/+bug/1311893/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
