[dolf1074]

steps to repro:

1. open openmoko-contacts
2. pick contact
3. push options
4. push modify
5. push back
6. redo from 2.

expected result:

You can do that forever

actual result:

The program sometimes become unresponsive. (it doesn't crash). The last line written to std is 'Xlib: unexpected async reply (sequence 0x6d3)!'

It should be fixed now. Code is going to be in unstable in some hours.
