When upgrading linux, my default currency went back to USD... but I didn't know. 

The first I knew was when I was importing QIF files (now in default USD into an
AUD account system)... I was given no error message, instead all my accounts
(including unspecified) were duplicated with the message "QIF Import: Name
conflicts with another account" which was not very helpful in this instance...
and the suggestions of gnucash user did not diagnose the problem. I had to read
the source to figure it out.

Hence I suggest that if there is a conflict causing the transactions to go into
a new account, that a quick little error message comes up to explain that there
is a conflict of transaction type preventing the transactions from being
imported into the suggested account. Alternatively if the new account name was
something like unspecified_USD then this would give a hint!

Thanks for gnucash, its great for a beginner like me to learn... but this one I
found difficult!
