qtwallet build from github source crashes on finding PoS blocks

gdb:

Code:

Trivial to fix:

Code:

nVersion,
vin.size(),
vout.size(),
- nLockTime),
- neodata.substr(0,30).c_str();
+ nLockTime,
+ neodata.substr(0,30).c_str());
for (unsigned int i = 0; i < vin.size(); i++)
str += " " + vin[i].ToString() + "\n";
for (unsigned int i = 0; i < vout.size(); i++)

The bug is now fixed in the last version.
