No automated build boot on my phone (Defy)

[Dino29]

Well, the app never actually dies. When I start it I get a black screen, and it just stays like that forever (until I tab out with the home button and force stop, which I didn't do when recording this log).
Nothing seem to happen after the part of the log I copied, here's the next entry :

[ 10-14 00:02:12.889 13283:0x33e3 D/dalvikvm ]
GC_EXPLICIT freed 336 objects / 11688 bytes in 66ms

and then nothing for 20 seconds (next entry is "Gsm Radio Signal level: 3" at 00:02:32).
