I can reproduce it on GDB 7.7, but can't reproduce it on GDB HEAD
(20140617) and 7.8 pre-release (gdb-7.7.90).

1. Start gdbserver
   $ ./gdbserver/gdbserver :1234 ./testsuite/gdb.base/wchar
2. Start gdb
   $ ./gdb
   (gdb) symbol-file ./testsuite/gdb.base/wchar
   Reading symbols from ./testsuite/gdb.base/wchar...done.
   (gdb) set debug remote 1
   (gdb) target remote :1234
   ....

qSymbol is sent.  You can use gdb 7.8 which will be released soon.
