Topic: Bitcoin-qt will not open in testnet mode (Read 880 times)

Hi All,

I am not new to programming, have been using Bitcoin for 6 months, and developing Bitcoin software since 4 months ago.
Got into this forum a few days ago, so, well, must post in newbies.

Have been running Bitcoin-qt on Ubuntu since february, and running it in testnet since one week or so.
Yesterday it stopped working with these messages:

1. a pop-up windows reading: An error occurred while setting up the RPC port 18332 for listening on IPv4: bind: Address already in use

2. a line in terminal reading: "Segmentation fault (core dumped)"

Any help will be greatly appreciated.
Thanks in advance.

Follows my Bitcoin.conf
