ok i tried in upgrading gdbm -> same problems So i downgrade to gtk2-2.2 / inkscape 0.38 (rpm -Uvh --force --nodeps) and everything return to normal.
You're overwriting GTK+ 2.2 with GTK+ 2.4, this most likely your problem.
Many, many things on your system depend on GTK+ 2.2. GTK+ versions are parallel installable, but you're not parallel installing different GTK+ versions... Maybe there is a gtk24-2.4 package out there you can find and install.
If nothing else, you can try doing 'rpm -ivh gtk2-2.4*' instead of -Uvh. This way you'll have both packages installed at the same time. The package installed last will likely overwrite any binaries and documentation, etc. But the shared libraries should be named in such a way as to not overwrite each other.
On my FC3 systems, for example, I have gtkmm2 and gtkmm24 installed. But in cases where packages aren't so conviently named, sometimes your only option is to use -ivh instead of -Uvh. (I've had to do this with curl several times.)
i guess that there is a way to do it, because _before_ the reboot everything was fine. so something happens during reboot that is not necessary.
Before the reboot, the old GTK+ 2.2 libraries are probably in memory in use by other running programs, even though they no longer exist on disk. Rebooting flushes memory, and the memory of the programs using that memory... And then they call crap out because they can't find the .so files they were compiled against.
That's my edumacated guess, anyways.
(i tried ro rebuild the gtk2-2.4.0..src.rpm but no succes) too bad.. Nobody here succeed on a fedora1 with inkscape 0.40 ?
If you compile GTK+ 2.4 and gtkmm 2.4 and the rest of the stack from source, install it all into /usr/local (or /opt, if you know a bit more about what you're doing and want better seperatation and/or deletability), you shouldn't have any problems at all. (Well, that is, except for the problem of compiling from source. *grin*)
If you can't find a way to parallel install gtk2 RPMs, then compiling from source may be your only other option.
