dbWriteTable segfaults on an admittedly weird data.frame with raw/bytea fields

[GoogleCodeExporter]

What steps will reproduce the problem?

 dbGetQuery(con,"CREATE TABLE byteatable (name text NOT NULL, val bytea, PRIMARY KEY (name))")
  sample.object <- list("one","two"); 
  ser <- serialize(sample.object,NULL,ascii=F);

  df <- data.frame(name=c("first","second"),stringsAsFactors=F);
  df$val <- list(ser,ser)

  dbWriteTable(con,"byteatable",df,append=T,row.names=F)

What is the expected output? What do you see instead?
All this was for a bytea insertion attempt. Instead, this happens:

 *** caught segfault ***
address (nil), cause 'memory not mapped'

Traceback:
 1: .Call("RS_PostgreSQL_CopyInDataframe", conId, dataframe, nrow,     p, PACKAGE = .PostgreSQLPkgName)
 2: postgresqlCopyInDataframe(new.con, value)
 3: postgresqlWriteTable(conn, name, value, ...)
 4: is(object, Cl)
 5: is(object, Cl)
 6: .valueClassTest(standardGeneric("dbWriteTable"), "logical", "dbWriteTable")
 7: dbWriteTable(con, "byteatable", df, append = T, row.names = F)

What version of the product are you using? On what operating system?

I have exactly the same problem on Ubuntu 14.04 with the newest R packages from 
CRAN.
