Unexpected Exception on ReIndex in logs

[Jason Moehlman]

Hello All,

I have a client program running on Linux that is crashing randomly  
with a segmentation fault.  The Valentina log is showing the following  
entries

Reindex of : id
Unexpected Exception on Reindex of : id

The program does not crash for every action, but the log entries do  
seem repeatable when the crash happens.   I was wondering what this  
log entry really means in Valentina terms.

I am not calling for any type of reindex in the code, the id column is  
a long long that is indexed and unique.  What type of internal  
selects, updates, etc would generate a log like this?

Is there any known issues of this type?

Thanks in advance.

Valentina 3.5.2, Linux build.
