New crash information added by DrKonqi

lokalize (1.2) on KDE Platform 4.6.1 (4.6.1) "release 390" using Qt 4.7.2

- What I was doing when the application crashed:

it crash, if I try to do this by starting lokalize from command line with
parameter of not .po file:
> echo "bla bla bla" > /tmp/geras.po
> lokalize /tmp/geras.po
and after that go Project > New project wizard

Comment 2 Adrián Chaves (Gallaecio) 2013-08-26 04:41:54 UTC 
I can reproduce this as well in Lokalize 1.5.
Comment 3 Adrián Chaves (Gallaecio) 2013-08-26 04:46:47 UTC 
*** Bug 291900 has been marked as a duplicate of this bug. ***
Comment 4 Adrián Chaves (Gallaecio) 2013-08-26 04:47:55 UTC 
Alternative steps from 291900:
1. echo "bla bla bla" > /tmp/geras.po
2. lokalize /tmp/geras.po
3. Close Lokalize.
Comment 5 Adrián Chaves (Gallaecio) 2014-07-30 05:27:13 UTC 
Maybe this has somethign to do with the “lokalize(26245)/kdeui (kdelibs) KXMLGUIClient::~KXMLGUIClient: 0x18f5f30 deleted without having been removed from the factory first. This will leak standalone popupmenus and could lead to crashes.” message that I can see in the terminal?
Comment 6 Christoph Feck 2014-08-16 15:09:13 UTC 
Nope, the crash here is related to Kross/Python scripting.
Comment 7 Nick Shaforostoff 2014-12-21 22:32:52 UTC 
this is fixed in master branch by avoiding any reaction to non-existing files specified on cmd line at all
