Description Hans Ulrich Niedermann 2008-06-01 14:53:20 UTC 
Description of problem:

  /usr/bin/mftrace around line 927:

  m = re.search ("\n!", log)
  start = m.start (0)

  No match found in log, m is None, None.start gives exception.
  Root cause is unknown, but this prevents lilypond rebuilds in rawhide.

  1.2.14-4.fc9

How reproducible:

  100%

Steps to Reproduce:
  1. cvs checkout lilypond
  2. cd lilypond/devel
  3. make mockbuild
  
Actual results:

MFINPUTS=. mftrace --encoding ./out/feta11.enc --no-afm -I . -I ./out/
--formats=pfa,pfb,svg feta11
mftrace 1.2.14
