I've accepted a friendship request, using 1.9cvs code from a couple of days, and I saw those two lines at the top of the page,
Notice: Undefined variable: local_sender_email in /home/httpd/tiki19/lib/messu/messulib.php on line 91
plus the normal output below:
tiki-friends.php?accept=userXXX
BTW, "friendship network" is missing from categories Feature in this website dev.tw.o! (so that, nowadays, it cannot be selected at bug report time)
To help developers solve the bug, we kindly request that you demonstrate your bug on a show2.tiki.org instance. To start, simply select a version and click on "Create show2.tiki.org instance". Once the instance is ready (in a minute or two), as indicated in the status window below, you can then access that instance, login (the initial admin username/password is "admin") and configure the Tiki to demonstrate your bug. Priority will be given to bugs that have been demonstrated on show2.tiki.org.
