[Bug 1758949] Re: brasero exited on a libisofs error

Fri Mar 30 22:09:32 UTC 2018

well - there is no "CVS pharmacy - Online Pharmacy - Transfer Prescription
or Refil2" but there is a folder called "CVS pharmacy - Online Pharmacy -
Transfer Prescription or  Refil<more characters>" - the "2" isn't present.

Is there any debug output that I can turn on to see what libisofs is
doing?
