The AppRun script in the root directory of the AppImage is missing double quotes in several places, one of the symptoms is if you have a file with spaces in the file name and try to open the file by running the AppImage with the file on the command line, then it splits the file name before trying to open it. Example: touch "/tmp/test file.txt" ./KDevelop-5.1.1-x86_64.AppImage "/tmp/test file.txt" opens the nonexistent files "/tmp/test" and "file.txt"
Confirmed. @Simon: Is this is a bug in `AppImageKit/AppImageAssistant.AppDir/package`?
Still a problem with the 5.2.0 AppImage.
@Kevin: `AppImageKit/AppImageAssistant.AppDir/package` is not maintained anymore since we have switched to a completely different codebase since. Please check out the appimagetool and linuxdeployqt.
Yeah, I'll have to do that eventually. I fixed the version of the AppImage repo a while ago since it did really weird things on build in newer versions (e.g. download source code of system libraries, compile them, and copy them over the system versions in /usr/lib). I'll happily check out the new code if this is gone.
Looks like you have ran into weird issues, please report such things at https://github.com/AppImage/AppImageKit/issues if you can. Our code should not do this. In any case, please have a look at https://github.com/probonopd/linuxdeployqt, too. By the way, the AppImage developers are at #AppImage on irc.freenode.net.
