attached is an "strace qtcreator" in case it might help

The same happens on karmic with qtcreator version 1.3.0-0ubuntu2~karmic1~ppa1.

[Mike Durham (mdurhamesq)]

just done the latest update (27/02/2010) including lots of Qt4 things, qtcreator still won't start.

[Mike Durham (mdurhamesq)]

just installed a fresh alpha 3 (15/03/2010) installed qtcreator, it still won't start.

seems generating the help collection on startup is causing long delays. workarounds for the moment include either
* disable the help system by running 'qtcreator -noload Help'
or
* leave qtcreator running until the help collection has finished generating (may take several minutes. the next start should then no longer have a delay
