joining files cut by avidemux gives errormessage

[jannesvdh]

First I cut useable part from 1 clip and save it with the disk icon to a (name)-edit file.
I do this for mutiple files.
I join these cut files in avidemux with the "append" function to generate one total clip.
Trying to save this total clip gives every time the following error.

Too short
the saved video is incomplete. The error occured at 00:00:19,602 (80%). This may happen as a result of invalid time stamps in the video.
In both cases I save with the "copy" function.

When I join "uncutted files" I have no problem.
What am I doing wrong.

Do you use the latest release (much better: the latest nightly build)?

If the problem persists, please provide more information, especially the output of MediaInfo for the source files.
