On linux:

PerfConfigurator --develop --executablePath
~/projects/mozilla/webapi/obj-x86_64-desktop/dist/bin/firefox
--activeTests tpaint --results_url file://${HOME}/talos.txt --output
tpaint_desktop.yml

talos -n tpaint_desktop.yml


This results in:

I have never personally seen this before.  We should at least catch
this error and print the command, as I can't even really guess what
the problem is from this traceback :(

Attachment: probable fix

this adds an additional filter to more efficiently ignore processes we don't care about and prints the command for debugging in the case of the case from comment 0 . So whether it is a 100% fix in practice is hard to say, but better.
