[R-gui] R-wxPython

[James Wettenhall]

Hi Vaidotas,

Thanks very much for your report about installing R, wxPython 
etc. on Debian.  I should mention that I have also been 
discussing this on the wxPython-users mailing list.  I've 
included a recent post by Robin Dunn below.  I'll definitely 
follow this up soon, but I'm a little busy at the moment, 
preparing for a microarray workshop at IBC in Cairns.

Best regards,
James

I have an idea of what the problem may be, but I need you to 
confirm it since I can't duplicate the symptom here.  Please 
place a debugger breakpoint in the wxPyApp::_BootstrapApp 
function and step down to the call to wxEntryStart.  Is the 
value of argv NULL?
