[giuspen]

could you try the latest from github for this issue?

[kerlerm]

Same for the latest self-compiled github binary. Problem persists.

[giuspen]

It would be useful if you could zip up the data that crashes for you and send it privately to me so I can reproduce. If possible, my email is in cherrytree help--about dialog

[giuspen]

will be fixed in 0.99.52
