gnucash not working

[Roger Grosswiler <roger@xxxxxxxx>]

hi guys,

gnucash won't start after launch. Launching it from shell gives the 
following:

[root@neo roger]# gnucash
ERROR: In procedure open-file:
ERROR: No such file or directory: "/usr/share/umb-scheme/slib/printf"

Any idea for a quick-fix?

Roger
