Hello, I am using Geany 1.37.1 (also tested latest git commit) on Manjaro Linux.
When I press "Ctrl + Shift + V" without switching to terminal tab in the Message Window, Geany crashes with error message:
```
/usr/include/c++/11.1.0/bits/shared_ptr_base.h:976: std::__shared_ptr_access<_Tp, _Lp, <anonymous>, <anonymous> >::element_type& std::__shared_ptr_access<_Tp, _Lp, <anonymous>, <anonymous> >::operator*() const [with _Tp = vte::platform::Clipboard; __gnu_cxx::_Lock_policy _Lp = __gnu_cxx::_S_atomic; bool <anonymous> = false; bool <anonymous> = false; std::__shared_ptr_access<_Tp, _Lp, <anonymous>, <anonymous> >::element_type = vte::platform::Clipboard]: Assertion '_M_get() != nullptr' failed.
中止 (核心已傾印)
```
Crash does not happen if virtual terminal is disabled in the settings or switching to terminal tab first. Pressing "Ctrl + Shift + V" also does not crash after switching to terminal tab and then switching to another tab.
Here is backtrace:
