Creating new AVD is terminated sometimes with exit code 1 with no patricular reason. Noticed for creation of second and futher devices. 

Current state of first device (Connected or Ready to use) doen't matter here as issue may occur for both cases. 

Issue also reproduced while trying to Overwrite existing AVD name.

Steps

• Start wizard to add android device
• Edit->Preferences->Devices->Add
• add first android device (android_1)
• add second android device (android_2)
