Error when one media file ends and the next starts

[Asajoh]

The problem occurs when I have several media files in one observation. As I am watching the videos and coding behaviours, the error pasted below happens as the video ends and the next starts. I have ticked the box to ask Boris to end state events at the end of each media file. Not sure if this bug is related to that. Also, Boris interprets the media files as having 1000 frames per second (but plays back at right speed regardless). This may be important as the bug seems to happen as a consequence of trying to convert time (utilities.py lines 196 and 979). The error output is below.

There is a possibility that these videos have variable frame rate, but I'm not too familiar with the recording software (xprotect). Windows just says they have 0 fps.

test can be done converting videos from VariableFrameRate to ConstantFrameRate

google "converting video variable frame rate to fixed frame rate"
