Hello Zoltan,

Sorry about that, I removed the check for f in svn revision 4468, and it will be in nano 2.2.2. Please let me know if this does not completely fix the issue.

In files.c (nano 2.2.1) the is_file_writable() function has the following assertion: 'assert(filename != NULL && f != NULL);'.

This checks if f is not NULL, but the function doesn't initialize variable 'f' before first using it in the assertion. This will result in an assert failure in random cases.
