iOS ipa is killed just after clicked on the app icon

Question

I build my ipa through my CI system. It's working well, my ipa is generated, as usual.

But when I install it on a device, and then tap on the app icon, the app launches and it's killed directly. I have this behaviour when the app is built on my macmini (OSX 10.10, Xcode 6.1).

When I build the app on my mac (OSX 10.10, Xcode 6.1), with the same command lines, the app is working well on my iPhone.

Any idea, why it's not working on the macmini ? It used to work well, but since 2 months it's doing this weird thing.

On both macs, I've got the right Certificates and mobileprovision. I checked the ipa generated, both have the embedded.mobileprovision with the right UDID.

Here is my code to build ipa :

xcodebuild -workspace MyProject.xcworkspace -scheme "MyScheme" -destination=build -configuration Release -sdk iphoneos7.0 ONLY_ACTIVE_ARCH=YES clean build archive


# Common path and partial filename
ARCHIVE_BASEPATH="${HOME}/Library/Developer/Xcode/Archives/$(date +%Y-%m-%d)/${XCODE_SCHEME}"

# Find the latest .xcarchive for the given scheme
NEW_ARCHIVE=$(ls -td "${ARCHIVE_BASEPATH}"* | head -n 1)

# Export 
xcodebuild -exportArchive -exportFormat "IPA" -archivePath "$NEW_ARCHIVE" -exportPath ./MyAPP.ipa -exportProvisioningProfile "My Distribution provisionning profile"

[Update] Here is the log of the crash :
