"java.lang.NullPointerException null" error

[fedsten]

I have an old MultiDoge wallet that I am trying to recover, but when I try to import the .wallet file into MultiDoge the following error arises:

Unable to load wallet "/home/user/MultiDoge/multidoge-data/wallet-unenc-backup/wallet-name.wallet" or backups. See help on "Wallet Backups" for more details.
The error was "java.lang.NullPointerException null"

I have tried it on both 0.1.7 and 0.1.1 (the one that I believe generated the wallet) and on two different machines, one Ubuntu and one Windows. The password seems to be correct as if I try to input an intentionally wrong password it gives a different error message ("Could not decrypt bytes").

Does anyone have an idea about what the problem could be related to?
