Comment 1 Michele Calgaro 2018-07-31 08:12:23 CDT

Hi Francois,
does this happen only in TDE? The backtrace seems to relate to QT lib, not TQt.

Comment 2 Francois Andriot 2018-07-31 13:09:25 CDT

Hello, the problem does not occur anymore on newer Linux distributions, so this bug can be closed.

Comment 3 Michele Calgaro 2018-07-31 19:54:56 CDT

Ok, thanks for the feedback :-)
