Seg fault on sentence from Europarl

I tried to translate this sentence from the Europarl English corpus into Portuguese and it segfaults.
```shell
$ echo "Obviously, there have been arguments, we had to go to conciliation, as the rapporteur and Mr Caudron reminded us a moment ago, since at the first meeting no result was achieved, and there had to be a second meeting, despite the fact that the figures were not excessive." | apertium -d . en-pt
Error in /home/drosset1/apertium-en-pt/apertium-en-pt.en-pt.t3x: line 4032: index > limit

Segmentation fault
#Obviamente, #hi tem havido #argumento, #ter ir
```
I get the same result in two different systems.
