Hugin crashing, any system file I can delete?

Hi there!

I reported this issue as Bug #1714441 but I don't know if it is a bug, haven't found any info anywhere.

I used Hugin a few times without problem but at one moment it crashed and I can't get it back to work. I'm on OS X Yosemite and Hugin crashes at start, and OS X sends a report to Apple, with an XML file:

<?xml version="1.0" encoding="UTF-8"?>
<report version="1.0" kind="exception">
  <system description="Mac OS X (Darwin 14.5.0 x86_64)"/>
  <stack>

    <frame level="1" function="_sigtramp " offset="00000000"/>
    <frame level="2" function="_sigtramp " offset="00000000"/>
    <frame level="3" function="MainFrame::SetGuiLevel(GuiLevel) " offset="00000000"/>
    <frame level="4" function="MainFrame::MainFrame(wxWindow*, HuginBase::Panorama&amp;) " offset="00000000"/>
    <frame level="5" function="huginApp::OnInit() " offset="00000000"/>
    <frame level="6" function="wxApp::CallOnInit() " offset="00000000"/>
    <frame level="7" function="wxEntry(int&amp;, wchar_t**) " offset="00000000"/>
    <frame level="8" function="main " offset="00000000"/>
    <frame level="9" function="start " offset="00000000"/>
  </stack>
</report>

Is there any corrupted file system or log or anything that I can modify or delete to solve this issue?

Thanks in advance for any tip or help!

Have a nice day!
