PTBatcherGUI displays wxWidgets debug alert upon startup on OS X 10.10

[Felix von Drigalski]

The title says it all. Occurs when clicking "Stitch!" in Hugin, which launches PTBatcherGUI. Using OS X Yosemite 10.10.4 and Hugin 2014.0.0.

wxWidgets Debug Alert

../include/wx/datetime.h(1740): assert "IsValid()" failed in GetTicks(): invalid wxDateTime

Call stack:
[00] ProjectListBox::GetAttributeString(int, Project*)
[01] ProjectListBox::AppendProject(Project*)
[02] ProjectListBox::Fill(Batch*)
[03] BatchFrame::BatchFrame(wxLocale*, wxString)
[04] PTBatcherGUI::OnInit()
[05] wxApp::CallOnInit()
[06] wxEntry(int&, wchar_t**)
[07] main
[08] start

Clicking Cancel to launch anyway seems to work, but it's irritating and seems to ask for admin privileges.
