[Roland Hieber]

Package: inkscape
Followup-For: Bug #785141
Control: retitle -1 inkscape crashes when opening any files if there are strange items in the recent files list

Applying the debug symbols patch patch from #733678, I get the following
backtrace:

The URI that is passed to Glib::filename_from_uri() in #8 is
"file://2014-09-14-dominik-openkeychain.osp" in my case, which seems to be an
item from the recent items list, as far as I understand the code in
Inkscape::ResourceManagerImpl::locateLinks(). This file obviously does not
exist, and please don't ask me how it got into the recent item list after all –
I cannot tell :D

So it seems glibmm cannot find the filename and throws an exception, which is
not caught by Inkscape and therefore causes the program to crash.
