Creator crashes on close when using a non-accessible settingspath

Steps to reproduce:

• open Creator with a non-accessible settingspath ( /t,p/8934ht9843ht worked for me )
• Creator starts and brings up lots of message boxes regarding the access of the config files
• close Creator - Creator brings up the message boxes again regarding writing the config files
• Creator crashes with segmentation fault (see attached backtrace)

Not sure if this might be Qt bug...
