I get this message, in the %s part I get just an empty string.

Message definition:
https://github.com/alrieckert/freepascal/blob/master/packages/fcl-
db/src/base/dbconst.pas

Used in this unit in two places:
https://github.com/newpascal/freepascal/blob/master/packages/fcl-
db/src/base/database.inc#L184

'RegisterDataset'
 method.

Any ideas of what can generate this error?

Edit:

database.inc is on file DB.pas, that contains the class TDatabase,
used by TSQLite3Connection (child of it).

Used in other class here

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i {

  TDBDataset  --------------------------------------------------------
-------------} Procedure TDBDataset.SetDatabase (Value :
TDatabase); begin  If Value<>FDatabase then    begin   
CheckInactive;    If Assigned(FDatabase) then     
FDatabase.UnregisterDataset(Self);    If Value<>Nil Then     
Value.RegisterDataset(Self);    FDatabase:=Value;    end;end;
 TDBDataset.SetTransaction (Value : TDBTransaction); begin 
CheckInactive;  If Value<>FTransaction then    begin    If
Assigned(FTransaction) then     
FTransaction.UnregisterDataset(Self);    If Value<>Nil Then     
Value.RegisterDataset(Self);    FTransaction:=Value;    end;end;
It must be setting the database or setting the transaction... The
problem is that this comes randomly and I can't debug this.
