A system assertion check has failed. Check the SQL Server error log for details

SELECT * FROM MyTable WHERE idIdioma=1034

i get the error:

A system assertion check has failed. Check the SQL Server error log for details

I look it in the log but it says that maybe network is wrong but the database is in my computer.

And if i execute first:
SELECT * FROMMyTable
and after that i execute:
SELECT * FROM MyTable WHERE idIdioma=1034

it works fine.
I readed the document:
http://support.microsoft.com/?scid=kb%3Ben-us%3B915050&x=17&y=14
but it does not work

My Table create script:

CREATE TABLEMyTable (
st INTEGER NOT NULL,
drvAutonomo BIT NOT NULL,
drvSupervisado BIT NOT NULL,
drvdriver BIT NOT NULL,
drvgateway BIT NOT NULL,
drvfw bit NOT NULL,

cePresencia BIT NOT NULL,
ceDatosPlanta BIT NOT NULL,
ceAutonomo BIT NOT NULL,
ceSupervisado BIT NOT NULL,
stat BIT NOT NULL,
idIdioma INTEGER NOT NULL,
titulo VARCHAR(128) NOT NULL,
descrip TEXT NOT NULL,
