Fixing lbdb corruptionEdit

I notice that sometimes my in-Vim address completion fails silently. Trying lbdbq . on the terminal shows the cause:

sort: string comparison failed: Illegal byte sequence
sort: Set LC_ALL='C' to work around the problem.
sort: The strings compared were `[redacted]' and `[redacted]'.
lbdbq: no matches

LC_ALL='C' does indeed work, but I don’t necessarily want to set that in the environment. So far, the workaround that has worked for me has just been to delete the problematic line from ~/.lbdb/m_inmail.utf-8.
