Huge usage of multi-parent tasks makes liblarch slow and raises tracebacks

[Izidor Matušov]

The attachement is the anonymized versions of my current task list. The loading time is much longer than before and applying a filter raises a traceback (Trying to remove node %s with no iterator) every time you apply a filter, e.g. selecting a tag or switching to WorkView.

To complete this bug:
1) Remove the traceback
2) Debug liblarch -> why it is so slow?
3) Optimize liblarch for this use case

Although this bug is critical and found in the testing period for GTG 0.3, it is a very very edge and rare use case. It should be solved for next releases.

I am getting the same problem with the daily ppa with gtg: 0.3.r1298~quantal1 and python-liblarch 2.2.0.r147_quantal1. My system is linux mint 14.

Getting the same myself.
