Comment 1 robert leleu 2012-10-03 13:28:21 UTC

don't take in account
the query used to feed the report was defectuous.
It showed twice a same field.

Comment 2 Jarosław Staniek 2012-10-03 19:29:34 UTC

Thanks for the report. Regardless of the reason, in ideal world the app should not crash so if you attach sample query that causes the crash we would be able to improve.

Comment 3 robert leleu 2012-10-03 19:43:36 UTC

I corrected it
I try to reprduce in a sample database.

Comment 4 Jarosław Staniek 2012-10-03 19:49:23 UTC

Yes, I noticed you corrected it. Since you're good at finding and analyzing issues, in the future I propose to first back up the database after crash like that before any attempts to fix the issue. This way reproduction can be much easier.

Comment 5 Jarosław Staniek 2014-06-27 21:56:42 UTC

@Robert
"the query used to feed the report was defectuous. It showed twice a same field"
Looks like a bug that we fixed in 2.8.3 or so.

Comment 6 robert leleu 2014-06-28 10:15:14 UTC

indeed

I use the neon kexi, and I had not recently experienced this bug.
