I am having some difficulties with some of Ericas utilities (beta 17).
'launch' for example gives me :

2012-07-19 10:10:20.443 launch[3204:707] *** Assertion failure in -[UIApplication init], /SourceCache/UIKit/UIKit-1914.85/UIApplication.m:544
2012-07-19 10:10:20.454 launch[3204:707] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'There can only be one UIApplication instance.'

terminate called throwing an exceptionAbort trap: 6

'findme' gives me 'Segmentation fault: 11'

Am on an iPhone 4 GSM running 5.1.1 with a jailbreak.
Any clue?
