No ert predicate fails. Tramp simply hangs.

The following command works as expected:

--8<---------------cut here---------------start------------->8---
# (test -e /Users/test1/tmp/tramp-test8687J1V/\أ\ص\ب\ح\ \ب\و\س\ع\ك\ \ا\ل\آ\ن\ \ت\ن\ز\ي\ل\ \ن\س\خ\ة\ \ك\ا\م\ل\ة\ \م\ن\ \م\و\س\و\ع\ة\ \و\ي\ك\ي\ب\ي\د\ي\ا\ \ا\ل\ع\ر\ب\ي\ة\ \ل\ت\ص\ف\ح\ه\ا\ \ب\ل\ا\ \ا\ت\ص\ا\ل\ \ب\ا\ل\إ\ن\ت\ر\ن\ت || test -h /Users/test1/tmp/tramp-test8687J1V/\أ\ص\ب\ح\ \ب\و\س\ع\ك\ \ا\ل\آ\ن\ \ت\ن\ز\ي\ل\ \ن\س\خ\ة\ \ك\ا\م\ل\ة\ \م\ن\ \م\و\س\و\ع\ة\ \و\ي\ك\ي\ب\ي\د\ي\ا\ \ا\ل\ع\ر\ب\ي\ة\ \ل\ت\ص\ف\ح\ه\ا\ \ب\ل\ا\ \ا\ت\ص\ا\ل\ \ب\ا\ل\إ\ن\ت\ر\ن\ت) && /bin/ls -ildn -w /Users/test1/tmp/tramp-test8687J1V/\أ\ص\ب\ح\ \ب\و\س\ع\ك\ \ا\ل\آ\ن\ \ت\ن\ز\ي\ل\ \ن\س\خ\ة\ \ك\ا\م\ل\ة\ \م\ن\ \م\و\س\و\ع\ة\ \و\ي\ك\ي\ب\ي\د\ي\ا\ \ا\ل\ع\ر\ب\ي\ة\ \ل\ت\ص\ف\ح\ه\ا\ \ب\ل\ا\ \ا\ت\ص\ا\ل\ \ب\ا\ل\إ\ن\ت\ر\ن\ت
--8<---------------cut here---------------end--------------->8---

And this command hangs and does not return:

--8<---------------cut here---------------start------------->8---

Maybe the command is simply too long for the shell?
