Hi:  
I am have some problems running GNURadio-Companion on my Quad-core  
Wandboard (ARM 7i hf) running Ubuntu 14.04.  
When I execute GNURadio-Companion I get a whole bunch of errors, here is  
the last few lines:

As you can see I lost most of the QT stuff that I need.  
Any Ideas on what I did wrong in the installation or configuration?

Thanks,  
Ed

Could possibly be some data corruption. Any chance you may have run out  
of  
disk space on your device?

Another possibility is that some of those blocks in particular use new  
features of GRC. Is it possible that you have multiple versions  
installed  
on your system where the older GRC is trying to load newer versions of  
the  
XML files?
