Dear Daniel,
a couple of Debian users reported a segfault of gpscorrelate with
incomplete gps tags, the original bug report is reported below, while
the full story is available at
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=487873. Can you please
have a look at it?
Many thanks in advance!
Cheers.
PS I did not explicitly forward the bug just after the submission since
I happen to remember that you subscribed to the bug notifications for
gpscorrelate, don't you?
