[BioC] readVcf fails when ALT field contains breakends and no symbolic allele

Hi Daniel,

I can't reproduce this error.

It looks like your version of R and Bioconductor packages are out of 
date. The current R version is 3.0.2 and VariantAnnotation is 1.8.2 
(release) and 1.9.7 (devel). Help for updating is here,

http://www.bioconductor.org/install/

Let me know if you get the same error after updating and send a small 
sample file if possible.

Thanks.
Valerie
