[QtCreator] Extraneous windows with garbage content when WelcomeTab=1 in QtCreator.ini

A workaround is to delete ~/.config/QtProject and never click on the "Develop" tab.

I am unable to reproduce this one.

Ok got it now..

So it is the "Qt Welcome" plugin which has the subtabs, which causes the issue.

The issue seems to be in ~/.config/QtProject/QtCreator.ini

[General]
WelcomeTab=1

When that is changed to 0 then the windows does not appear.

This happens wíth:

$ apt-cache policy libqt5core5
libqt5core5:
  Installed: 5.0.2+dfsg1-3ubuntu1~raring1~test2
  Candidate: 5.0.2+dfsg1-3ubuntu1~raring1~test2

$ apt-cache policy qtcreator
qtcreator:

     2.7.0-0ubuntu3 0
        500 http://fi.archive.ubuntu.com/ubuntu/ raring/universe amd64 Packages

I don't observe this bug with libqt5core5 5.0.1+dfsg-0ubuntu4 and qtc 2.7.0-0ubuntu4~raring1~test5.

Removing ~/.config/QtProject/QtCreator.ini makes no difference, still works fine.

I'm in Qt 5.0.1. and the problem does not appear. So it seems Qt 5.0.2. specific.

It seems to happen when WelcomeTab gets set to 1 from 0 in QtConfig.ini of Qt Creator...

So a workaround would be:
sed -i 's/WelcomeTab=1/WelcomeTab=0/' .config/QtProject/QtCreator.ini

I guess we could hard-code that setting somehow until the bug is resolved?

Found the place in src/plugins/welcome/welcomeplugin.cpp and added a distro patch plus built the new bug fix release Qt Creator 2.7.1 against Qt 5.0.2. One can still trigger the original problem with the 2.7.1 (for reason unknown so far, help browsing related?), but it's away after a restart which was the bigger problem.

That was on a local build, and pushed the same build to ppa:ubuntu-sdk-team/testing - JP (and the rest of the SDK team), please test the whole functionality of the 2.7.1-0ubuntu1~raring1~test2 after it is installable from that PPA so that the new raring Creator can be copied to SDK Release PPA. It has the same Ubuntu plugin version as the latest (custom) SDK PPA release, as can be seen in the changelog.

Copied to SDK Release PPA, thanks to JP and others for testing. I opened up a follow-up bug #1181192 to track the remaining issue.

This bug was fixed in the package qtcreator - 2.7.1-0ubuntu1
