I am creating xml files for my RDS block, in order to be able to use
it together with GRC.
I had forgotten to close a tag in an xml file that I had put into
/usr/local/share/gnuradio/grc/platforms/python/blocks/
The result was that I couldn’t run GRC anymore, it would exit with
these messages on the console:
Traceback (most recent call last):

Josh, shouldn’t GRC ignore malformed xml files (or maybe warn),
instead of failing to run?
Sorry, I am not yet familiar enough to submit a patch for this…
