It's possible to create a FrameInformation object that's not backed by
any frame data. In this case, fi_ is NULL and loadFrameTree() does not
run a dissection. However, we run epan_dissect_cleanup() unconditionally
in the destructor, even if edt_ is uninitialized. This causes a crash
when wireshark is closed.
Convert edt_ into a pointer. Run the cleanup only if we ran the
dissection before.
The issue can be reproduced by applying a display filter that makes the
list of the packets smaller than the packet list window. Right click
onto an "empty" part of the packet list and select "Mark/Unmark Frame".
Exiting wireshark at this point causes a segmentation fault
Thread 1 "wireshark" received signal SIGSEGV, Segmentation fault.

Do not use QDir::separator() as a directory separator. QT internally
uses "/" as separator on all systems, including Windows. The zip files
were not unzipped into target directory because splitting path on
QDir::separator() in ProfileModel::cleanName() returned only one part
(there weren't any "\' in file name, only "/").
Qt documentation for QDir::separator() mentions:
"You do not need to use this function to build file paths.
If you always use "/", Qt will translate your paths to conform to
the underlying operating system. If you want to display paths to
the user using their operating system's separator use
toNativeSeparators()."

This reverts commit 9445403f95.
cf_select_packet frees the buffer backing the dissection result
(cf->edt) which results in use-after-frees when callers try to access
the contents. See for example this call trace:
* PacketList::selectionChanged
* cf_select_packet(cap_file_, row)
* frameSelected(row) -> ByteViewTab::selectedFrameChanged
* addTab(source_name, get_data_source_tvb(source))
get_data_source_tvb returns the buffer that backs the dissection and
must remain valid even after dissection has completed. If this is not
done, then a possibly expensive redissection must be done in order to
populate the byte view. The temporary memory savings are not worth it.
