INVALID error message fix needed

Here is your repaired project file anyway.

Here is what I did to fix it - you might be able to do it yourself the next time it happens.

  1. Open the .mlt file in a text editor - anything besides notepad because it does not read the line endings correctly.
  2. Search for every instance of INVALID.
  3. Several lines below the line <property name="text">INVALID</property> look for
    <property name="mlt_service">qtext</property>
  4. Change qtext to qimage
    <property name="mlt_service">qimage</property>
  5. Repeat for every INVALID
  6. Save

Meanwhile, I will think more about what can be causing this or how to avoid it. I think the amount of memory you have is fine unless… yeah, you do not have enough free mem.
