After getting updated to Seamonkey 2.3, my tabs were restored, but the urls weren't loaded, leaving all tabs empty, except for the first one. Neil Rashbrook did let me do some investigation. I'm seeing the same error with the sessionstore.json file (new profile) in the latest Seamonkey trunk build. I'm not seeing this error using this sessionstore.json file with the latest Firefox desktop trunk build (after having it renamed to sessionstore.js). So I guess Firefox contains already a fix for this error situation. I noticed this error in the error console using the lates Seamonkey trunk build: Error: uncaught exception: [Exception... "Could not convert JavaScript argument arg 0 [nsISHEntry.stateData]" nsresult: "0x80570009 (NS_ERROR_XPC_BAD_CONVERT_JS)" location: "JS frame :: jar:file:///C:/Users/mw22/Desktop/seamonkey-2.5a1.en-US.win32/seamonkey/omni.jar!/components/nsSessionStore.js :: sss_deserializeHistoryEntry :: line 2827" data: no] I haven't attached the sessionstore.json file, because I don't know if it contains sensitive data, but if someone needs to have it in order to be able to fix it, let me know and I'll mail it to you.

We need to port parts of bug 551225.

patch, incorporates also missed fix from bug 647028.

(In reply to comment #3) > I don't see the point of this change. It's time for me to stop blindly copying code :( Pushed with nit fixed: http://hg.mozilla.org/comm-central/rev/a7169a94d871

Misak, the reporter was talking about SM 2.3 in the beginning. If this needs to be backported to aurora/beta, please request accordingly. We still have a chance to land things for 2.3, but it won't be long and the door will close.

Comment on attachment 549573 [details] [diff] [review] patch The parent m-c bug 551225 will be in Firefox 6 so this should land on comm-beta as well I think.
