After doing that for a few of my desktop icons, plasma crashes. I was unable to identify the icon, it may be a dangling pointer that leads to the crash later.

Related to a video file, probably not an image file.
(In reply to Christoph Feck from comment #1) > Related to a video file, probably not an image file. That was my first thought based on the backtrace as well. I actually have some video files on the desktop, in webm format. They are not next to the image file that caused the crash though. I looked into .xsession-errors later that day and found that there were some unresolved symbols reported for a library. Wanted to paste that here but it's now gone from the file after doing a fresh login :-( Since the crash I also did a dist-upgrade which repaired my browser (iceweasel did not start in between), so something was broken. My guess is that the cause was a bad library and the error during dlopen was not properly caught. I'd consider this a bug and would expect a good error message about the broken library. On the other hand this was probably caused by a build problem and you can't catch all of them at runtime. I leave it up to you to close the bug or investigate further. I wonder how to trigger this by modifying a shared library to break in dlopen...
Hello! This bug report was filed for KDE Plasma 4, which reached end-of-support status in August 2015. KDE Plasma 5's desktop shell has been almost completely rewritten for better performance and usability, so it is likely that this bug has already been resolved in Plasma 5. Accordingly, we hope you understand why we must close this bug report. If the issue described here is still present in KDE Plasma 5.12 or later, please feel free to open a new ticket in the "plasmashell" product after reading https://community.kde.org/Get_Involved/Bug_Reporting If you would like to get involved in KDE's bug triaging effort so that future mass bug closes like this are less likely, please read https://community.kde.org/Get_Involved#Bug_Triaging Thanks for your understanding!
