Bug#642913: deskbar-applet: infinte loop in templates extension

[Jędrzej Potoniec (smaug)]

Package: deskbar-applet
Version: 2.32.0-1+b2
Severity: normal
Tags: patch

Dear Maintainer,
it tried twice to add Deskbar applet to my Gnome Panel and both
times I ended killing deskbar-applet, because it was using 100% of the
CPU and something like 2.5GB of memory for 1.5 hour. The second time I
straced the process and discovered that during some filesystem traversal
it went down into wine symlinks which lead from some subdirectory of my
home to the ~ itself (my filesystem isn't a proper tree, but a graph if
considering symlinks).
I couldn't get to the applet properties (or to it's menu, I think it was
busy-waiting for extension), so by selectively removing files from
/usr/lib/deskbar-applet/modules-2.20-compatible
I narrowed it down to the plugin `templates'.

I don't know or use python, but for me it works if in templates.py, in
line 196 condition 'not os.path.islink(file_path)' is added.
