TLV value runs over buffer

[Hans en Dory]

I attached a piece of the log file with the invalid QMI message. The message occurred after I plugged in the dongle but before I made a connection. 

I hope this will shine more light onto the problem.
Oh, btw, I did not loose the connection and was able to send this message to the mailing list.

Thanks,

 Yes, that
 would be great.  I have my suspicions though: Huawei are
 fond
 of AT commands, and they tend to have a
 few unsolicted commands starting
 with ^. 
 24074 happens to be 0x0a5e in little endian, or LF + ^ if
 decoded as ASCII.  Just a hunch...
