I don't believe it is a connection problem on my part. I have no trouble accessing the Internet at all, pretty smooth line right now.

Title:
  Synchronization failed via Ubuntu One / Tomboy Web with exception:
  "Collection was modified; enumeration operation may not execute"

Status in “tomboy” package in Ubuntu:
  New

Bug description:
  Binary package hint: tomboy

  I have ~460 notes, and synchronizing doesn't work with the following
  messages (tomboy --debug) :

  [DEBUG 12:21:41.998] Saving 'Flowchart Konsultasi Laptop'...
  [ERROR 12:21:41.998] Synchronization failed with the following exception: Collection was modified; enumeration operation may not execute.

  [DEBUG 12:21:41.999] Saving 'Maven pom.xml'...

  I do have many special characters on my notes (I save a lot of XML
  code, Java code, PHP code, etc.)
