This is on a 32-bit Fedora 12 system, with current-as-of-today GIT of
Gnu Radio and UHD. GRC identifies
as:

GNU Radio Companion v3.4.0-115-g62768eed

I have Python 2.6.2

Marcus,
How recent are these errors? Has the offending commit been identified?
There’s been some work done on gr-uhd very recently. Any chance the
problem has been solved for you?

I haven’t identified the offending commit. If I remember to, I’ll see
if I get these with most recent
Gnu Radio/gr-uhd/GRC.

Ive seen that. Its pretty harmless though. When you delete the number of
mboards, some of the widgets get hidden, and still tries to access the
objects. I havent yet figured out what in the update logic causes
this…

OK, so with a Gnu Radio fetched just about 30 minutes ago. Create
multi-channel (two will do), single-mboard UHD source, and manipulate
things like frequency, gain, etc:
