It is caused by your code trying to send the contact .csv file, which is 
present in the sample project but isn't in your own. Either comment out the 
attachment being sent in your code or copy the file over and you will have no 
crashes anymore.

I dont think thats the case, because i couldnt find contact.csv file in the 
source.im also attaching images and text files. Also it was working fine for 
more than two month.. now only im facing this problem.

Any chance the fix proposed in issue #53 , changing the if(len)  to if(len > 0) 
 would fix the problem. The poster of issue #53 observed that the length 
returned can be negative.
