Many thanks for writing a bug report.

For a deeper analysation we need the following from you:

1) core dump
or better output from backtrace of gdb from the core dump

2) which mysql client library do you use?

3) exact version of your mysql server

actually there is no mysql-client installed and also no mysql-sever.
mysql-common is 5.0.67-0ubuntu6
but opening via the normal open dialog works fine, so this might not be the problem.
and because normal opening works it is not a critcal bug.

Thank you for the bug report.

Does that happen with any model? If not, can you attach one of the models that cause the crash?

i still have a similar issue on wb 5.1.5.
but now it crashes not only on projects which have been moved and are not at the old location.
sometimes wb crashes, sometimes i get a dialogbox which (correctly) says:
Cannot open document '/.../database-model.mwb'.
Could not open file /.../database-model.mwb: No such file or directory

Hi 

Please try again with 5.1.9 beta and reopen the bug if the bug is still present.
