Thanks for the tip to start gnucash from a terminal and thus being able to see the progress text.
The text shows clearly that things are no good. To understand the meaning of the text is beyond me,
but it is indeed a good starting point for "googling". Thanks.
I think a "solution" can be found about "the gnucash 2.4.7-3.1.2 problem" in opensuse 12.1
on the following adress :

I agree with the remark made on this forum on nov. 28. Quote : "I will wait for the team to produce and push
a patch to solve this problem" etc.
For me it means that I am going to use, for the time being, kubuntu 11.10.
Here, gnucash 2.4.7-1 works flawlessly.
