Comment 1 Jarosław Staniek 2014-05-03 19:46:13 UTC 
Confirmed, recent port to Qt4 completely ignored reports.
Comment 2 Adam Pigg 2014-05-03 19:48:22 UTC 
Yes, i looked at the backtrace and instantly blamed you :)

Sooner tableview is ported the better, then there is no confusing q3 code!
Comment 3 Jarosław Staniek 2014-05-03 20:30:30 UTC 
Thanks for the deep analysis guys.

@Adam regarding opened views, maybe there's something wrong with this hack: KexiWindow::isDesignModePreloadedForTextModeHackUsed() - happens only for queries since only queries use Text mode.
Comment 4 Jarosław Staniek 2014-05-03 20:31:35 UTC 
@Adam yeah, we have time before 2.9.0. This crash shall be fixed quickly and temporarily though since it's similar case to the table view.
Comment 5 Jarosław Staniek 2014-05-09 23:25:17 UTC 
Git commit 1cff375660e7d42df3e5740964049baae128dbdd by Jaroslaw Staniek.
Committed on 08/05/2014 at 08:19.
Pushed by staniek into branch 'master'.

Fix crash introduced in reports after porting forms to Qt4

(that was commit 1c53aa8b9e09681)

Put the page navigator is put aside of the report area's horizontal
scroll bar like we do in table and form views.

Comment 6 Ian Balchin 2014-05-12 08:12:46 UTC 
I was about to submit same bug this morning, but caught it as a recently fixed bug. Did git pull and rebuilt, confirm also appears fixed.
