Does it happen with that software only? Can you do the same pasting to e.g. kolourpaint? And, the backtrace is completely useless. Hello Pino! _Environment: _P4, openSUSE Linux 10.2, KDE. Standard install, CmapTools 4.09_ __Problem:_ Attempting to paste an image from kpfd into a Cmap annotation causes kpdf to crash _Additional checks:_ I checked it with the following: - kolourpaint - OpenOffice Draw - The GIMP - Krita - MS Word under CrossoverOffice (Wine+) Each of these programs was OK. What puzzles me is that once it gets into the KDE clipboard, why should the paste target affect kpdf? _Further testing:_ I ran a few more tests: 1. Run CmapTools & load the target document 2. Load the pdf document into kpdf 3. Copy the image to the clipboard 4. Close kpdf 5. Paste the clipboard to the target Cmap document - and get a few numbers, but no image. I suspect that it tries to treat the clipboard image as text. Next: 1.-3. as above 4. Run kolourpaint and paste the image - OK. 5. Select and recopy the image from the kolourpaint canvas 6. Paste the clipboard to the target Cmap document - and again get a few numbers, but no image 7. This time kolourpaint crashes! _Summary:_ I think that there are several problems here: 1. It seems ridiculous that a paste from the KDE clipboard should affect the task from which it was copied - no matter how badly behaved the receiving task happens to be. 2. It is not a specifically kpdf issue (You're off the hook!) 3. The CmapTools program is written in Java and uses JRE 1.6.0. I suspect that the place to which I wanted to paste the image may be a text-only window, in which case I should have got nothing at all or perhaps an error. There is definitely something amiss here. _What next:_ 1. Perhaps you could forward this material to the relevant KDE folks. 2. Once they have some idea of what's going on, either they or I can co-ordinate with the CmapTools people. 3. In any event, I'm Cc-ing cmapsupport. 4. I'll need a bit of guidance to set up for proper backtraces.
