Is there a bug with Ark?

If anyone does not mind downloading the following 19 MB file: http://www.libsdl.org/extras/win32/cross/mingw32-linux-x86-glibc-2.3.tar.gz can they explain why if I try to open it with Ark or preview in Ark via Konqueror 3.51 it gives an error of "unsupported file format" but if I do a tar xvzf operation on it, it expands out quite neatly? Oh BTW did anyone notice that after upgrading to KDE 3.51 right-click creating zip files creates a *capital* extension ZIP? This used not to be the case. -- Tux #395953 resides at http://samvit.org playing with KDE 3.51 on SUSE Linux 10.0 $ date [] CCE +2006-02-24 W08-5 UTC+0530
