Hi all

I have just done a fresh install of Linuxcnc 2.8 & then upgraded it using buildbot.
Now when I start linuxcnc from the command line it reports 2.10.0.xxxxx

I have run the stepconf wizard to create a generic starting profile & when I try to open it it crashes giving some sort of QT/python error that I don't understand.

I have attached the errorrs.
I'm sure this must be something obvious but not sure what I need.

Thanks
Alex

PS cannot attach the linuxcnc generated error report !?!
Here it is pasted...

Yep that did the trick.

If its not part of the automatic dependencies would it be possible to get this put on the qtdragon doc page?

Thanks
Alex

The dependency list has an old library (my system has both libraries so I didn't notice)
I am looking to update the dependency and also have changed QtDragon to not crash if the library is missing - it's just for the HTML setup page.

Sorry about the trouble - thanks for the report.
