Thanks for the report.

Gnus' code will construct a command line like this:

mu find --nocolor --muhome=~/.cache/mu <QUERY HERE> --format=plain --fields=l

Would you try running this with a sample query, and sending a sample
output (I hope it's just a list of file names). That should help narrow
down whether it's a problem sending the query in, or a problem parsing
the output.

Thanks,
Eric
