I disabled the plugins but it's still the same error. I don't see the "New Project Dialog" :-/
OK, this might be a GTK error, so we need more information.
Could you type this to terminal and tell us what it outputs:
----
You were able to disable the plugins so you can see other dialogs, could you test if you can see these dialogs:
- Settings -> Enviroment|Editor|Compiler and Debugger
- Tools -> Configure tools
If you can see the Settings -> Enviroment dialog, go to View and disable the "Start here" page and test to create a project again.
----
And last, could you download
this simple project file, extract it ("unzip TestConsole.zip") and try to open it from:
- Code::Blocks -> File -> Open
- From terminal "codeblocks TestConsole.cbp"
