Thank you for taking the time to report this bug and helping to make Ubuntu better.

However, processing it in order to get sufficient information for the developers failed (it does not generate an useful symbolic stack trace). This might be caused by some outdated packages which were installed on your system at the time of the report. Please upgrade your system to the latest package versions. If you still encounter the crash, please file a new report.

Thank you for your understanding, and sorry for the inconvenience!

I can confirm this crash. Please report upstream.
Here is the meaningful part of the backtrace:

#6 0x00007f9607380d80 in strlen () from /lib/libc.so.6
#7 0x00007f95f13a45b0 in gcpTextTool::OnGetData (this=0xc63ba0,
clipboard=0xf9d030, selection_data=0x7fff102da5f0,
info=<value optimized out>) at texttool.cc:624

Thanks you, Jean. Since the part of your backtrace is very small, I made a complete one with all available symbol tables and a valgrind because it crashes in a segmentation fault. I will shortly put an entry on the mailing list of the developers.

In the end, I opened a bug upstream: https://savannah.nongnu.org/bugs/?25888 which is now fixed (for the 0.10.x branch only).
