Custom UI Form crashes QGIS in Ubuntu

Original Redmine Issue: 11982
Affected QGIS version: 2.6.1
Redmine category:forms

I've made a small test project with simple vector layer and custom UI form in Qt4 Designer for editing this layer (as described in Nathan's blog: http://nathanw.net/2012/03/30/custom-qgis-feature-forms-value-binding). But when I've selected geometry on layer and pressed View feature form button QGIS silently crashed. That was in Ununtu 14.04 (QGIS 2.6.1).

After that I've tried the same in Windows 7 (32bit) in various QGIS versions: 2.01, 2.2, 2.4, 2.6 -- all of then open my custom UI form well, as intended.

What was at Ubuntu command line after crash:
