Bug fix, see code

Not sure how this will work.

I got this exception (on my dev-qif-export):

09-19 22:45:34.569  14102-14102/org.gnucash.android W/Bundle﹕ Key account_uid expected String but value was a java.lang.Long.  The default value <null> was returned.

It seems that at some time a long is set for account_uid and after that a string is asked. So I search where a long is set for account_uid.

My App is now in a unrecoverable state and I have uninstall it and install again.
