Null Pointer Exception at beagled/Mono.Data.SqliteClient/SqliteDataReader.cs:418

[Martin Ludwig <martinludwig gmx net>]

Hi dashboard-hackers,

since some days beagle gets an null-pointer Exception after 1 or 2
minutes of running. Queries during that timeframe work, after that the
beagle-daemon is dead.

Any hints of what is going wrong?

here are the relevant lines of the Log-Files:
