hugin won't start: "invalid window dc"

[clepsdyrae]

Hi -- Kubuntu 16.10, added the nightly repo which appears to have last been updated 2017-04-10 (2016.3.0.84a397fa5e9a).

Running hugin, I see a splash screen and an immediate failed assertion:

ASSERT INFO:
../src/gtk/dcclient.cpp(1520): assert "IsOk()" failed in Clear(): invalid window dc

BACKTRACE:
[1] wxWindowDCImpl::Clear()
[2] ImagesTreeCtrl::SetOptimizerMode()
[3] OptimizePanel::Init(HuginBase::Panorama*)
[4] MainFrame::MainFrame(wxWindow*, HuginBase::Panorama&)
[5] huginApp::OnInit()
[6] wxEntry(int&, wchar_t**)
[7] main
[8] __libc_start_main
[9] _start

If I click "Continue" many times, the program appears to start and work (though I haven't fully tested.)

I can't reproduce the issue on Fedora.
Trying a blind fix in changeset 282b5e7ba8f0. This breaks at least for me nothing.

Thanks! I'll try it when it comes to the nightly ppa.

In case it helps: I click "Continue" 12 times to get the program to start.

Also: the version in the standard ubuntu repo did not have this issue.

Also, just FYI, from the CLI invocation of hugin:

Latest nightly works without issue! Thanks!
