Well, I dug into telepathy-logger code and it seems that it's possible for the code to legally construct TplSearchHit with null account. 

This can happen when the account manager is not ready at the time of searching or when the account was removed (but the log files are still there). So I'd say it might not be really a bug but an undocumented "feature" of the telepathy-logger rather then a bug.

I tried removing one of my Jabber accounts from Telepathy and then I was able to reproduce the crash everytime I tried to search in logviewer (without the patch). With the patch the crash is OK.
