What steps will reproduce the problem?
1. Grab any test set, train some sigs, then move a tiff out of the way. You can 
use my test set which exists on 
lgchrm14:/home/colettace/projects/eckley_worms/TimeCourse. There the file 
01/Day1_09.tiff isn't there.
2. Train a classifier using the trunk. The command I ran was:
~/src/wnd-charm/wndchrm/trunk/wndchrm train -l -m `pwd` TimeCourse.fit
3. Crash occurs when file 01/Day1_09-l.sig is reached.

What is the expected output? What do you see instead?

Please use labels and text to provide additional information.


The crash occurs at TrainingSet::AddImageFile() line 1461, when a call is made 
to our_sigs[sig_index].sig->Clear ();

Notice that the variable n_sigs is only greater than 0 for this edge case 
situation, and thus that's the only time line 1461 is hit.
