Right click on applet at computer startup made syncdaemon crash

WORKAROUND
1. Quit the Ubuntu One client. From the applet select Quit. Then open a Terminal (Applications > Accessories > Terminal) and run the following to quit the syncdaemon.

u1sdtool -q

2. Delete the old metadata. In a Terminal run.

rm -rf ~/.local/share/ubuntuone

3. Start Ubuntu One as you normally would Applications > Internet > Ubuntu One

Logs from SD.

Another thing to note is that log files are 1098 bytes sized... isn't that too little?

Hi Naty,

By any chance you used trunk and then started an old client? ;)

I mean, if you started a client using trunk code, your metadata was migrated and now the system-wide client can't read it (look that's trying to read metadata v.6 which is the new metadata version)

Cheers,

[Guillermo Gonzalez (verterok)]

I'm marking this as invalid, as we can't make old client understand new metadata :)

Thank you duanedesign!!

The fix worked for me.
