Debug symbols for `qca` (arch linux package name) is actually installed by
recompiled it from source, enable "debug" and disable "strip" in
/etc/makepkg.conf
------------
After investigation, seems that the crash is actually caused by private key,
not CA certificate file.
Test code:
```
#include <QtCrypto>
#include <QDebug>
int main()
{
QCA::Initializer init;
qDebug() << "isSupported(\"pkcs12\"):" << QCA::isSupported("pkcs12"); //
got "true"
QCA::ConvertResult convRes;
QCA::KeyBundle keyBundle = QCA::KeyBundle::fromFile("/opt/****/cert.p12",
"************", &convRes);
qDebug() << "convRes:" << convRes; // got "0"
const QCA::PrivateKey pkey = keyBundle.privateKey();
// QCA::PrivateKey::canDecrypt() calls QCA::PrivateKey::isRSA()
// which calls QCA::PrivateKey::type()
// which calls `static_cast<const PKeyContext *>(context())->key()->type()`
const QCA::Provider::Context *context = pkey.context();
auto pkey_context = static_cast<const QCA::PKeyContext *>(context);
const QCA::PKeyBase *pkey_base = pkey_context->key(); // got nullptr
const QCA::PKey::Type pkey_type = pkey_base->type(); // segmentation fault
qDebug() << "pkey_type:" << pkey_type;
return 0;
}
```
