This can be triggered with just
% xvfb-run perl -Iblib/lib -Iblib/arch -e 'use Wx; use Wx::PropertyGrid'
The problem seems to be in the wxwidgets3.0 package, whose build logs
on armel and armhf have this:
dpkg-shlibdeps: warning: symbol _ZNK14wxCommandEvent5CloneEv used by
debian/libwxgtk3.0-0/usr/lib/arm-linux-gnueabi/libwx_gtk2u_propgrid-3.0.so.0.1.0
found in none of the libraries
Olly says this is probably related to #752733 but he's not certain.
I'm cloning a separate bug against wxwidgets3.0 at this point.
The current plan for libwx-perl is to fix the test suite not to crash
but skip the failing tests, and then downgrade this to 'important'. The
attached patches are a first stab at this. I ran out of time tonight and
haven't even run a full 'make test' with these yet, but I don't really
expect problems.

Subject: [PATCH 1/2] Fix Wx::_load_plugin() segfaulting when
wxPluginManager::LoadLibrary fails
FIXME: _load_plugin() is aliased to *DynaLoader::dl_load_file
in Wx::Mini, should this return undef somehow or does 0 work?
