When adding TTXT chapters to a file, the duration is set incorrectly., adding several minutes or more. I am using version 0.4.6-DEV-rev3968M. The parameter that results in this is -add chapters.ttxt:chap.

A sample movie info follows (note that the duration in track 3, the chapter file, is more than 2 minutes more than the other tracks):
