Hi,

Most probably when such errors occurs the problem is usually in the file it is trying to parse. Try putting a breakpoint at that point and see the name of the file and try to open the file using imread in commandline and also try opening the file normally, in most cases the file is corrupted or the file extension is not proper.

Here are the links to questions similar to yours, hope this helps.
