Hi all,

I was downloading a debian package from an ftp server. In a Konqueror window I displayed the target directory of the download. Now when I refreshed this window and hover with the mouse cursor over that *.deb.part file Konqueror crashed in the moment where the tooltip would have appeared otherwise.

It is not necessary that the file is being downloaded in order to trigger the crash. A *.deb.part file that is just lying around will do "fine". Just make sure to reload the directory and try out the tooltip.
backtrace:

IMHO there seem to be 2 bugs (though not necessarily): 
First the deb kfile_plugin crashes with an incomplete file. Second Konqueror or the kfileview tries to use that kfile plugin even though its service might not be reliable.

No matter how robust these kfile plugins are, they might always encounter a incomplete file with just not enough information in it to make a tooltip from it. Konqi should just say "partially downloaded file" in this case.

Thanks for reading,
Andreas
