There have been reports of history sync failing because of this exception, thrown by Utils.anno() when the URI that was passed is null. It looks like there's an edge case where places provides an invalid or null URI and we don't handle it gracefully. If anything we could do better error reporting here.

Hello I join this bug. (Installed 1.5). I'd like a lot to use Sync well. Hoping to get a good fix soon. Just as a last trial I deleted Firefox history and now sync works.

i do not understand the explanation? what to do? what does this mean? please clarify what to do about fixing the problem? I unchecked history in sync and it seems to work, but that doesn't seem to be mentioned here? again what to do about fixing this? is it a bug that can be fixed ?

Here's a wallpaper patch that makes the history engine handle invalid URIs in the places DB gracefully. Wallpaper because this doesn't fix the root cause, though I'm not even sure Sync could do anything about the root cause. Hopefully with the logging in place we'll be able to collect some data on these URIs.

Hopefully this is the right place to put this: Sync still does not work on one of my computers. Works on P4 Win XP 32 bit. 3.6.12 Does not work on AMD 4-core Win7 64 bit. 3.6.12 Tried disconnect, connect. sync now. Tray message says "Error While Syncing". Does not show "Last Update:..." on mouse-over like the XP machine. My background is in midrange database systems, so I won't be much help in debugging on my own. But, I can usually follow instructions with only minor casualties.

This may look like the same error.
