latest version of gtksourceview lib is installed:
No update candidate for 'libgtksourceview-3_0-1-3.24.11-2.10.i586'. The highest available version is already installed.

Install no errors...
Is this because of 32 bit ? Then why ?

To whom it may concern:

Got snapper-gui working by installing this package:
http://rpmfind.net/linux/opensuse/tumbleweed/repo/oss/i586/gtksourceview-devel-3.24.11-2.10.i586.rpm
which is NOT in the tumbleweed system repo 32 bit...
