Description of Problem: dia is failing with a libpng warning: Application was compiled with png.h from libpng-1.0.12 libpng warning: Application is running with png.c from libpng-1.2.2 libpng error: Incompatible libpng version in application and library Gtk-CRITICAL **: file gtkcontainer.c: line 713 (gtk_container_add): assertion `widget != NULL' failed. dia: relocation error: /usr/lib/dia/libcustom_objects.so: symbol __ctype_b_loc, version GLIBC_2.3 not defined in file libc.so.6 with link time reference Version-Release number of selected component (if applicable): 0.90-8 How Reproducible: every time Steps to Reproduce: 1. start dia and watch stderr Actual Results: dia exits Expected Results: dia starts Additional Information: I did not really install 8.0 from a cd... I rather only upgraded a bunch of the RPMS. Could this be a problem? As a workaround for this problem, I used the dia srpm to rebuild the binary rpm and reinstalled it. I had no troubles afterwards. dia is not the only program that had this problem. Other packages include: gnome-dictionary gnome-session
You need to upgrade using the installer for the upgrade to work reliably. If you get the final versions of all packages then this should work fine.
