[R] random crashing GLM

I am trying to fit a GLM model using R (version 0.64.1 Win95) onto a
dataframe(dtse) consisting of 3348 rows with 4 variables:
- 3 factors: (c)31 levels, (m)12 levels (s)9 levels)
- 1 integer: (n)
The data consists of counts and is strongly overdispersed.

I try fit the following model
dtse.glm<- glm(n~s+c+m, data=dtse, family=quasi(link=log, variance=mu))

When I issue this command R sometimes answers, but sometimes (using the
same dataset) simply crashes without any error message in the R-console.
Only the standard Win95 error-dialog appears.

Can anybody advise me how to overcome (workaround) this problem.
