#16 Problem to load .gsd files

Since several releases there is a load problem for .gsd files with DGManager, also with the current version 1.2.4224.
My use case is to save DG-100 tracking data with DGManager in the format .gsd as a backup. Later I would like to retrieve this file content.
Obviously there is an issue with the format of the time stamp concerning each track point:

Error message from DGManager:
EXCEPTION: Die Eingabezeichenfolge hat das falsche Format (input string has wrong format).

Extract vom .gsd file (1.2.4224):
[DATE]
1 = 2011-09-26-19:27:48
[TP]
1 = 001,2011-09-25:11:36:27
[001,2011-09-25:11:36:27]
1 = 48391838,,9423042,,093627,250911,25.09.2011 09:36:27,10,4130000
2 = 48391713,,9423146,,093943,250911,25.09.2011 09:39:43,370,4200000
...

The latest version which had no issues to load this format seems to be 1.0.3309. Also in this case I may provide the corresponding entries of the .gsd file for comparison:
[DATE]
1 = 2011-09-26-19:25:28
[TP]
1 = 001,2011-09-25:11:36:27
[001,2011-09-25:11:36:27]
1 = 48391838,9423042,093627,250911,10,4130000
2 = 48391713,9423146,093943,250911,370,4200000
...

Do you have an idea what's going wrong with the more recent SW releases?

No improvement or change with 1.2.4301
