On some devices, having jzlib enabled (as of 22e4653) seems to cause data corruption:

This issue needs to be investigated (the author's devices all seem to behave).
Might be related to smack+jzlib not working on SMP devices (see also OpenFire).
disable compression due to strange bugs. see #85
The issue also happens with recent asmack (using system compression) against prosody, so it must be a SMACK/asmack bug.
This has been worked around by disabling compression in a7a5f29 a long time ago. Closing.
