Heh, nice ARK bug report !! Some guy reported that a 400 Mb ( !! ) tar.gz file is causing ARK crash.. That's ok, could be a bug, but see their log report: ... /bin/tar In file tools/qgarray.cpp, line 126: Out of memory ... Well, i'll try to figure out a better way to handle this better than add more swap or another memory chip :-) This specific bug will be reassigned to core kdelibs developers, since ARK uses ktar class, not owns implementation ( how beatifull is KDE class structures :-), but i thought that other file types can be suffer of same disease... Hard is create a compressed file large than 400 Mb with a slow harddisk..
